When I’m painting away from the studio, I’ve learned that the best art kit is the one that is simple, lightweight, and familiar. I don’t want to carry everything I own—I want a small selection of tools that I know I can rely on wherever I decide to paint.
That’s one of the reasons I’ve become increasingly interested in painting on a smaller scale, especially ACEOs. Their compact size fits naturally into a travel kit and gives me another way to enjoy watercolor wherever I go.
What Is ACEO? Understanding ACEO Art Cards
If you aren't familiar with the term, ACEO stands for Art Cards, Editions & Originals. ACEO Cards are miniature original works of art cut to a standard size of 2.5 x 3.5 inches.

This small format has become incredibly popular in the art community. ACEO Art is easy to collect and display, making it especially appealing to people with limited wall space.
Finished pieces can be kept in collectors' folders, placed in mini-frames, or displayed on specially designed magnetic mounts.
For me, the appeal is simple: a tiny piece of paper can still hold a complete little painting—and it gives me another reason to keep creating.
Why I Love Painting ACEO Cards
I’ve always enjoyed painting small, but ACEO painting takes that idea a step further. The compact size makes each piece feel manageable, while also opening up some fun possibilities for artists and collectors.

- Space-Saving: For exhibiting artists, this modern format makes it possible to showcase a wide variety of work at exhibitions and craft fairs without taking up much table space.
- No More Measuring: Instead of cutting up expensive watercolor sheets and hoping each little piece turns out perfectly, the paper is already made to the right size.
- True Accessibility: The smaller format creates a more affordable entry point for people who want to own original art. It also encourages collectors to find creative places to display it.
- Perfect for Small Spaces: How many times do we hear, "I love your work, but I have absolutely no wall space left!"? With ACEO Cards, your fridge—or almost any magnetic surface—can become a personal art gallery.
And honestly, I cannot wait for my four-year-old great-niece, Ava, to paint me an original ACEO for my studio!
How I Approach ACEO Watercolor Painting
When working on such a small surface, I like to keep my process straightforward. Some artists prefer to mask the edges with tape to create a crisp white border. It looks especially lovely on paper with a perforated edge, giving the finished piece the appearance of a postage stamp.

For holding the paper in place, some artists use tiny corner magnets. My preferred method for ACEO watercolor painting is even simpler: wet-mounting.
I use a small sheet of clear perspex or smooth plastic, dampen the surface with a wet brush or spray, and lay the dry paper directly onto it. The water tension holds the paper flat and securely in place while I paint. Once the painting is completely dry, it lifts away effortlessly.
This simple setup makes watercolor ACEO painting feel much less complicated, especially when I’m painting away from the studio.
My New Fuumuui ACEO Watercolor Paper Set
In the studio, I typically stick to A4 and 30 × 40 cm sheets. In my travel bag, I usually carry a Fuumuui 8 × 8-inch rough paper block along with some A5 sheets.
But this year, I’m adding two exciting new elements to my travel pack: Fuumuui Postcard paper and their all-new ACEO watercolor paper set, which comes with handy protective sleeves.

The set includes:
- High-quality ACEO watercolor paper in stamp & rounded-corner styles
- Individual crystal-clear protective sleeves
- A magnetic fridge mount for displaying finished ACEO Cards
- A portable round brush, sized nicely for the compact ACEO format
I also like having smaller sheets available for warming up. Before diving straight into a larger painting, I always loosen up by practicing on A5 or smaller paper first. It helps build confidence so that by the time I touch the larger sheets, I’m already in the “creative zone”—painting without overthinking and simply going with the flow.
From ACEO Painting to Collectible ACEO Art
One of the things I enjoy most about ACEO Art is how naturally a painting can become something collectible.

Once my piece is fully dry, I sign and date the back before slipping it into one of the crystal-clear protective sleeves. If I’m really happy with it, I can then place it directly into the magnetic mount and put it on our kitchen fridge for everyone to see.
That little finishing process makes ACEO Painting feel different from simply making a quick sketch. Even though the artwork is tiny, it still becomes a finished original that can be kept, displayed, gifted, or collected.
For Artists, it’s also a wonderful way to create a larger variety of original works. For Collectors, the small size makes it possible to enjoy original paintings without needing a large amount of display space.
Taking ACEOs on the Go
To make outdoor painting a little easier, I recently picked up a lightweight tripod for my travel easel and a compact travel camera for capturing my plein air adventures. I’m still searching for the perfect travel stool, though!
That’s what I love about ACEO Art and painting on the go: you don’t need a complicated setup. A few small sheets of paper, some paints and brushes, and a lightweight kit can be enough to turn a quiet moment outdoors into a little piece of art.
I hope you all enjoy the approaching summer months. May your sketchbooks and watercolor pads be absolutely full of beautiful art—and wonderful memories!
