When I first wondered about painting on cardboard myself, I of course googled it…and now Google is sending some of you to *this* entry for info on ‘painting on cardboard.’ So here’s what I’ve learned from my experience with cardboard so far:

Artists have been painting on cardboard for over 100 years (e.g. this Picasso, 1900).

Cardboard’s main advantages in my opinion:

— It is non-precious. I find I paint more freely on corrugated cardboard than any other substrate. Even before I make the first brushstroke I feel like “this is an experiment.”

— It’s free! It’s abundant!

— I can work on an oversize piece of cardboard, and “crop” my painting with a knife after the fact.

— It’s already manufactured. I’m repurposing something that would otherwise be recycled or discarded. Zero carbon footprint.

— It’s immediate. Cut, paint.

— I like the way it takes paint. (I use heavy body, artist’s grade acrylics.)

— It’s fun to see what graphics may already be printed on it (see this painting for example) that I can leave visible.

— It’s lightweight.

— If it gets beat up a little on the edges or corners, who cares?!?

The best cardboard for painting is double thick; two corrugated layers sandwiched together. To find the best stuff, think of large/fragile/expensive items, and go to stores that sell them — electronics, bicycles, appliances. I’ve found that local bike shops are happy to save me their bicycle cartons.

Take a box cutter along to cut down the cartons for easier transport (as a courtesy I also haul away the leftover scraps and recycle them myself, so I don’t leave a mess for the shop owner).

Large Home Depot-type stores tend to bale their cardboard immediately, unfortunately, although I did score a refrigerator box at Lowes by being there at precisely the right time once.

Keep your cardboard stash dry, don’t store in a shed or humid environment. Avoid cheap pulpy cardboard (such as cartons for tools from Harbor Freight ).

For relatively temporary works (years, not decades) just paint right on the cardboard. It will be absorbent, which can be annoying or useful depending on your medium and intentions. Bare areas will be subject to fading, especially if displayed where sunlight strikes it.

To make it much less absorbent but still retain its cardboardy look, apply thinned down acrylic medium before painting on it; do both sides equally to minimize warping.

For more permanence, prime both sides with house primer, gesso, or acrylic medium. Give both sides an equal number of coats to minimize warping.

For grunge appeal, you can purposely tear off the top layer here and there to expose underlying corrugations, and/or leave some of the arrows, ‘this side up’ labeling, hand hold holes, big copper staples, UPC codes, and other original artifacts intact or partially painted over.

Tip for hanging  cardboard paintings: 

Cut scrap of cardboard and glue onto back of painting as anchor for a hanging wire or string. It’s surprisingly strong, and is in keeping with the cardboard theme. You can also make hang tags, title placards, portfolios to transport your cardboard masterpieces in, and so on, all from cardboard. Once you have large sheets of it laying around, all kinds of uses start popping up.

You can “reverse engineer” how to make a cardboard box by looking at an already-made one, draw a layout on a big panel, cut/score it, paint it, then fold/glue/staple it into a sturdy decorated box that will last for years with reasonable care.

I painted the self portrait (below) on cardboard, as well as the following paintings:

That’s it for now…I’ll add more if I think of something else.

Good luck!

Self Portrait February 24 2011, freehand from a b/w photo I took yesterday

Acrylic on corrugated cardboard, slightly smaller than life size (area shown is 13 x 15, panel is 19 x 27)

Using just two colors of paint: Burnt Sienna and Unbleached Titanium White

We had a “snow day” today, many Portlanders stayed home from work. This painting is what I did with my snow day. No my hair doesn’t have snow on it, that’s just the color it has decided to be now that it’s grown up.

I enjoyed the process.

The product, however, is way more conservative than I’d like…it’s a baby step along the path of moving stylistically to where I’d rather be.

This is the  most recent practice project in my current fling with attempting likenesses. I think the painting probably looks better than the subject, but since it’s a self portrait I’m not keen on posting the reference photo just to prove the subject looks worse than the painting.

Fast forward to 2025! Some of the links above may be moldy…following are fresher ones:

Cardboard as Canvas: An Exploration of Its Use in Early 20th Century Parisian Modern Art

The history of cardboard as a backing for oil paintings, particularly its prevalence in early 20th-century modern art in Paris and the use by artists like Picasso, touches upon a fascinating intersection of material innovation and artistic experimentation. The use of cardboard as an artistic support holds a notable place within the narrative of modern art, especially during a period of significant upheaval and creative exploration in Paris. This report aims to provide a comprehensive overview of this practice, drawing upon historical context and examples.

The story of cardboard as an art medium begins with understanding its origins and initial applications beyond the realm of art. The term “cardboard” itself has roots in the mid-19th century, with Anne Brontë using it in her 1848 novel.¹ Initially, “cardboard” was a somewhat vague term referring to any type of heavy-duty paper used for various practical purposes.¹ In Britain, during the mid-1800s, corrugated cardboard found its first application as a lining for gentlemen’s top hats, designed to absorb perspiration and improve ventilation.² Across the Atlantic, in the United States, its utility expanded to packing lamps and other fragile goods.² Commercial production of paperboard boxes began as early as 1817 with the English firm M. Tiverton & Son, followed by German manufacturers around the same time.³ These early boxes, made from thick paperboard, were first adopted in the transportation industry in France during the 1840s for carrying silkworm moths and their eggs.³ The latter half of the 19th century saw further innovations, with corrugated paper patented in England in 1856 and corrugated boxboard patented in the US in 1871 for shipping.³ These developments in the 19th century, making cardboard increasingly available for commercial use ³, laid the groundwork for its later adoption by artists seeking accessible and unconventional materials in the early 20th century.

Even before the dawn of the 20th century, paper and cardboard had begun to appear as supports for artistic endeavors, particularly for sketches and studies.⁴ Due to its flexibility, paper was not significantly used for paintings requiring rigid support, such as egg tempera or oils, before the 20th century.⁴ However, its absorbent qualities made it ideal for water-based media like watercolor, which has been almost invariably applied to paper since the Renaissance.⁴ Some artists, like Giovanni Battista Lusieri at the end of the 18th century, worked almost entirely in watercolor on paper.⁴ The 19th century witnessed improvements in paper manufacturing, making it available in larger sheets and rolls, further facilitating its use.⁴ While finished oil paintings on paper were limited, it proved suitable for plein air sketches, with artists like Pierre-Henri de Valenciennes and Camille Corot extensively using paper for this purpose.⁴ Cardboard, being a thicker and more rigid form of paper, also found its way into artistic practice during this period. Museums today hold paintings on cardboard that date back as far as the late 16th century.⁵ By the late 19th century, artists like Charles Conder, associated with the Australian Impressionist movement but who also spent time in Paris, were using large sheets of cardboard for oil paintings.⁴ The increasing availability and familiarity of cardboard, stemming from its growing commercial applications throughout the 19th century, likely contributed to its gradual acceptance within artistic circles as a viable, albeit unconventional, support.

The early 20th century witnessed Paris solidify its position as the global epicenter of artistic innovation. This period was marked by the emergence of various avant-garde movements, including Cubism, Dadaism, Fauvism, and Expressionism, all of which challenged the long-established norms and traditions of the art world.⁷ This environment of radical experimentation fostered a climate where artists felt increasingly liberated to explore unconventional materials and techniques.¹ The traditional hierarchy of materials, which often favored costly supports like stretched canvas, began to be questioned.¹ Cardboard, with its utilitarian origins and humble nature, became an appealing alternative for artists seeking to break free from these conventions.¹ Its easy availability, malleability, low cost, and potential for upcycling made it an attractive option for artists navigating financial constraints or those wishing to make a statement through their material choices.¹ The very act of using such a commonplace material could be seen as a challenge to the perceived preciousness of traditional art and an embrace of the everyday, aligning with the philosophies of movements like Dadaism.¹ Furthermore, the structural properties of cardboard, such as its flatness and ability to be cut and assembled, resonated with the artistic aims of movements like Cubism, which focused on fragmentation and the representation of multiple perspectives.⁸

Within this vibrant Parisian art scene, Pablo Picasso stands out as a pivotal figure who extensively utilized cardboard in his artistic practice.

4.1 Early Use of Cardboard in Paintings (1900-1907)

During his formative years in Paris, particularly between 1900 and 1907, Picasso, like many of his contemporaries, often faced financial hardship.⁹ Living in the artists’ quarter of Montmartre, he frequently resorted to using readily available and inexpensive materials, including “throwaway cardboard,” as an alternative to costly canvases.⁹ This economic necessity played a significant role in his early adoption of cardboard as a painting support. A crucial moment in Picasso’s early career in Paris was his 1901 exhibition at the prestigious Vollard Gallery.¹⁰ For this significant show, Picasso employed cardboard as the support for many of his works.¹⁰ The choice of cardboard was not solely driven by its lower cost compared to canvas; it also offered the practical advantage of drying faster, allowing Picasso to produce a larger body of work within a limited timeframe for his Parisian debut.¹⁰ Art critic Felicien Fagus even noted Picasso’s remarkable productivity during this period, suggesting he completed around three works a day, although this might have been an exaggeration.¹⁰ Among the works from this period that utilized cardboard as a support are notable examples. “The Fourteenth of July (Le quatorze juillet)” from 1901 is documented as oil on cardboard.¹¹ Another painting from the same year, “Old Woman (Woman with Gloves),” also employed cardboard as its base.¹² A self-portrait by Picasso from 1901 is also recorded as being painted on cardboard.¹³ Furthermore, “Margot (Waiting),” painted in 1901 and exhibited at the Vollard Gallery, is specifically identified as oil on cardboard.⁹ Picasso’s willingness to use cardboard for such an important exhibition early in his career indicates that he was not averse to employing unconventional materials for presenting his artistic vision to the Parisian art world. This decision, partly born out of necessity, also reflects a broader artistic climate in Paris where experimentation and a departure from traditional practices were gaining momentum.

4.2 Cardboard in Picasso’s Cubist Explorations and Sculptures

Picasso’s innovative spirit extended beyond painting to the realm of sculpture, where he again embraced cardboard in groundbreaking ways, particularly during his exploration of Cubism. The early 1900s, coinciding with the rise of Cubism, saw cardboard emerge as a notable art medium, with Picasso’s “Still Life with Guitar” becoming a celebrated example of this trend.¹⁴ This work, created around 1912, marked a radical departure from the traditional methods of carving or molding in materials like bronze, wood, or marble.⁸ Instead, Picasso constructed his “Guitar” from humble materials such as cardboard, paper, string, and wire, cutting, folding, threading, and gluing them together to create a three-dimensional representation.⁸ This innovative approach aligned perfectly with the core tenets of Cubism, which sought to represent objects from multiple viewpoints and break down traditional notions of form and perspective.¹⁸ The “Guitar” constructions, both the original cardboard version and its later iteration in sheet metal, effectively demonstrated the formal considerations of Cubism by presenting the different planes of the instrument in a three-dimensional arrangement within real space.¹⁸ The use of flat planes of cardboard to build up the form of the guitar mirrored the fragmentation and assemblage characteristic of Cubist painting.⁸ As Picasso himself explained, these cut-up pieces, differentiated by color to represent perspective and planes, could be assembled to create a “sculpture”.¹⁸ The cardboard “Guitar” was not an isolated instance of Picasso’s use of this material in three dimensions. He also constructed other open-form works from cut or found pieces of cardboard ²² and even painted on vessels and created sculptures from cardboard.²⁴ This consistent engagement with cardboard in his sculptural endeavors highlights Picasso’s willingness to push the boundaries of traditional art forms and explore the expressive potential of everyday materials.

4.3 Expert Perspectives on Picasso’s Cardboard Works

Art historians and conservators offer valuable insights into Picasso’s motivations, techniques, and the significance of his cardboard pieces, revealing that these works are not merely byproducts of financial constraints but integral to his artistic innovation. Scott Gerson, a conservator who has studied Picasso’s “Guitar” constructions, challenges the long-held view that the 1912 cardboard version served simply as a preliminary model for the 1914 sheet-metal “Guitar”.²⁵ Gerson’s analysis suggests that Picasso likely disassembled the cardboard guitar to create paper templates for its various elements, some of which might have even been incorporated back into the sculpture.²⁵ This perspective elevates the cardboard “Guitar” beyond the status of a mere maquette, highlighting its role in Picasso’s exploration of originality and the process of replication.²⁵ Jeffrey Weiss further emphasizes Picasso’s intention for the “Guitar” to be a prototype that could be reproduced, underscoring the artist’s radical ideas about the ephemeral nature of art.²⁵ The fact that the cardboard “Guitar” remained disassembled for decades until its acquisition by MoMA reinforces this notion of material instability and the work’s existence beyond a singular, fixed form.²⁵ Beyond the “Guitar,” studies of Picasso’s paintings on cardboard also provide important information. An investigation into Picasso’s 1905 painting “The Acrobat Family” on cardboard revealed the inherent fragility of this support, noting its acidity and signs of degradation.²⁶ This highlights the conservation challenges associated with these works, emphasizing the need for careful preservation to ensure their longevity. The use of cardboard by Picasso, therefore, was not just a practical choice but a deliberate engagement with the material’s properties, pushing the boundaries of artistic expression and challenging conventional understandings of art’s value and permanence.

While Picasso is perhaps the most renowned artist associated with the use of cardboard in early 20th-century Paris, he was not alone in this experimentation. Several other artists working in the city during this period also turned to cardboard as a viable painting support, reflecting a broader trend within the modernist movement. Dada artists, known for their embrace of the unconventional and everyday, also utilized cardboard in their artistic creations. Marcel Janco, though primarily active in Zurich during the height of Dada, created famous Dada masks from cardboard, which were used in performances at the Cabaret Voltaire.¹ Kurt Schwitters, another key figure in Dada, employed cardboard in his large-scale installation “Merzbau” in Hanover, demonstrating the material’s potential for monumental constructions (though Schwitters was based in Germany, Dada had strong connections to Paris).¹ Amedeo Modigliani, who spent significant time in Paris, also used cardboard extensively throughout his artistic production, particularly for sketches, smaller compositions, and personal works.²⁷ Félix Vallotton, a Swiss artist associated with the Nabi movement in Paris, utilized gouache and oil on cardboard as early as 1897, as seen in his work “Street Scene in Paris”.²⁸ Edouard Vuillard, another prominent member of the Nabis in Paris, employed oil on cardboard for his painting “Luncheon” in 1901.²⁹ Louis Legrand, working in Paris around the turn of the century, created an oil on cardboard portrait of an elegant woman in 1900.³⁰ Maximilien Luce, a Post-Impressionist painter active in Paris, used oil on canvas mounted on cardboard around 1910 for his depiction of floods near the Pont Neuf.³¹ Pierre Bonnard, also a key figure in the Nabi movement in Paris, frequently painted on cardboard or wood during his early career around 1900.³² Even artists with connections to other movements or locations, like Charles Conder, who was part of the Australian Impressionist movement but spent time in Paris, used cardboard for oil paintings as early as around 1888.⁴ While primarily associated with Munich, Wassily Kandinsky exhibited paintings on cardboard alongside canvas, suggesting a broader acceptance of this support within early 20th-century avant-garde circles that had connections to Paris.³³

The motivations behind this widespread use of cardboard were likely varied. Beyond the economic factors that drove Picasso’s early adoption, cardboard offered other advantages that resonated with artists of the time. Its non-precious nature, as noted by a contemporary artist, might have encouraged a more experimental and less inhibited approach to painting.³⁴ The abundance and ease of obtaining cardboard, often from discarded packaging, further contributed to its appeal.¹ The ability to easily cut and crop cardboard allowed for flexibility in composition.³⁴ For some artists, the act of repurposing a discarded material aligned with the artistic philosophies of movements like Dada, which challenged bourgeois values and embraced the everyday.¹ The table below summarizes some of the key artists mentioned who utilized cardboard as a painting support in early 20th-century Paris:

While cardboard offered numerous advantages for artists, its use as a support for oil painting also presented technical and archival challenges that needed to be addressed to ensure the longevity of the artwork. Unlike traditional canvas, cardboard is inherently acidic and can absorb oils from the paint, potentially leading to degradation of both the support and the paint film.³⁵ To mitigate these issues, proper preparation of the cardboard is crucial. One common method involves sealing the cardboard with a substance like shellac.³⁹ Shellac acts as a barrier, protecting the painting from the natural acids in the cardboard and preventing the oil from seeping into the material.³⁹ Following the sealant, applying gesso is a recommended step.³⁹ Gesso, a mixture of chalk, binder, and pigment, creates a receptive surface for the paint to adhere to.³⁹ For oil paintings on cardboard, applying multiple layers of gesso, often at least four, is advisable.³⁹ Some artists also suggest sanding the gessoed surface between coats for a smoother finish.³⁹ While these preparatory steps are important, the inherent nature of cardboard means that artworks on this support might still be more susceptible to environmental factors compared to paintings on canvas.³⁶ However, despite these potential issues, history offers examples of artworks painted on cardboard that have endured for significant periods. Edvard Munch’s iconic painting “The Scream,” with one version executed in oil, tempera, and pastel on cardboard in 1893, has lasted due to careful preservation.³⁴ Museums around the world also hold paintings on cardboard dating back centuries, indicating that with proper preparation and care, these works can indeed have longevity.⁵ Contemporary artists who choose to paint on cardboard often employ meticulous methods, using double-walled cardboard, multiple layers of paint, acrylic gel mediums for adhesion to wood supports, and protective varnishes to enhance color and guard against light and moisture.⁵ These practices demonstrate a continued awareness of the technical considerations involved in using cardboard as a lasting artistic support.

In conclusion, the use of cardboard as a painting support in early 20th-century Parisian modern art was not an anomaly but rather a significant aspect of the era’s artistic landscape. Driven by a confluence of economic necessity, a spirit of experimentation, and a desire to challenge traditional artistic norms, artists like Picasso and many others embraced this humble material. Picasso’s groundbreaking use of cardboard in his Cubist constructions, particularly the “Guitar,” exemplifies the innovative spirit of the time, pushing the boundaries of sculptural form and material. While cardboard presented technical challenges for oil painting, artists employed various methods of preparation to enhance the durability of their work. The story of cardboard in Parisian modern art serves as a compelling illustration of the movement’s broader themes: a willingness to embrace the unconventional, to find artistic merit in the everyday, and to redefine the very definition of art. For the reader seeking further information, resources such as the Picasso Experts website ⁴³ and the extensive body of work by renowned Picasso scholars like John Richardson ⁴⁴ and Diana Widmaier Picasso ⁴⁵ may offer deeper insights into Picasso’s specific techniques and motivations for using cardboard.
