4 Colors + eyeshadow compact: A Step-by-Step Guide to Making a Tiny Travel Watercolor Kit
For years I’ve carried a full set of Prang watercolors for field sketching…but now it feels cumbersome.
So in keeping with the idea of Lean Startup, I set out to make a Minimum Viable Watercolor Field Kit. I asked “What’s the smallest, simplest watercolor set I need to create basic field sketches?”
Spoiler alert: There are tons of folks making compact watercolor sets for fun and profit. This is the approach I used and it worked for me. If you’re interested in other ideas, the Googles has gobs of inspiration for you.
I set aside a few days to figure out how to get the biggest bang out of the smallest kit.
Step 1: Set the criteria & contents.
How small is small? Turns out it’s 5" x 3.5" x 1.75". I found an old neoprene zipper pouch that was a great size for a tiny kit. This became the criteria: Make the entire kit fit in the pouch. (Having the pouch as a design constraint reminded me of the Jeff-Hawkins-block-of-wood-into-Palm story.)
So what’s the most basic kit? The only items I really need in the field: watercolor paints, waterbrush, and an old sock to use as a wrist-rag*. (Note: paper, pencils, pens are also needed, but those are consumables that don’t need to fit in the kit.) I was eager to try an extremely limited palette: 3 primaries and maybe a neutral. So the paint container could be quite small. Once I had the goal size and contents, I was ready to seek out the optimal container for the paints.
Step 2: Transforming an eyeshadow compact.
A fellow nature-journaler posted on the Nature Journal Club Facebook group about her tiny sketch kit (Check out Fay’s post…it’ super cool!) She mentioned using a small mirror compact, so with that in mind, I headed to the makeup section at Target to see what I could find.
Viola! The Wet & Wild 4-color eyeshadow kit was perfect! A great size, nice handfeel, and only $2.99. Win!
I would have been okay with only 3 colors, but having the 4th section meant I could add a neutral which would increase the range of hues possible.
 Dig out the eyeshadow with a toothpick.
 Clean the pans completely.
 Pick paints
I went with 3 primaries & a neutral.
- Red = Quinacridone pink (Daniel Smith)
- Yellow = Cadmium yellow hue (Windsor & Newton Cotman)
- Blue = Pthalo blue green shade (QoR)
- Neutral = Shadow violet (Daniel Smith)
The paints are the only expensive part of this kit. But the investment was worth it because I can refill the palette multiple times from the tubes.
 Make a palette sample card.
I find it really helpful to have a sample card on the palette that shows the colors and basic mixes.
 Fill the pans & fill in the sample color card
 Stick on the sample color card and add a loop
To aid holdability, it’s handy to have a ring or loop on the back of a palette. These smartphone loops are perfect! And inexpensive.
Step 4: Complete the kit
For the brush, I used a Sakura Koi mini waterbrush. This model has a plug for the water container, so it can be carried disassembled in 2 parts. #Win.
Last of all the wrist-rag*. It’s an old sock with the foot cut off. Best if it’s mostly cotton and a light color (white or grey) so you can see if your waterbrush is clean.
Step 5: Test-drive it
The kit is ready to test-drive!
First use: make a watercolor mixing chart. Making a mixing chart was new to me, so thankfully there are lots of awesome people out there who show the step-by-step. My goal was to practice mixing with the limited palette, and also to see how much I could vary the saturation to go from a very light wash to an intense pigmented wash.
I chose a wheel layout with the primaries in a “peace” sign layout and browns and greys in the middle. The strongest pigment is on the outside ring, then 5 levels of successively light washes towards the center.
Since I had a neutral, I could see how the neutral wash interacted with the colors and washed from mixing (put the neutral wash in when all the colors were dry.) The shadow violet wash is the darker stripe in each hue strip.
I also played around with coaxing out some greens. Nature has a lot of greens.
Then I made a sample painting.
Step 6: Take it on the road!
All set and ready for action!
Finding the container and ordering the cellphone loops took a couple of days. Making the kit took a good part of a day. Most of the time was spent waiting for the paint to dry. The mixing chart took about 90 minutes. It was a simple and fun process, and now it’s easy to toss the kit in my bag any time I leave the house.
* The magic of the wrist-rag. OMG the wrist-rag is a game-changer. When used with a waterbrush, you don’t need to take lots of extra water, brushes or rags into the field. This tip comes from the amazing and generous John Muir Laws (You should follow him.)
Total cost was about $17, plus the $30 for paint.
