After experiencing some success with plein air drawing (as detailed in the tree-drawing post), I was consumed by my own hubris and set out to assemble a field painting kit. This is a well-tread road, but I wanted something small enough to stuff into a backpack or fanny pack.
I cobbled together a kit with a mint tin palette and a small tupperware container for water. These are attached directly to the book with magnets: I used a pair of small neodymium magnets for the water container and a magnetic metal clip for the palette. This setup has been working out really well, even in situations where I'm sitting on the ground or somewhere similarly uneven. It's not great for standing work, though, since the water needs to stay perpendicular to the ground.
I've been thinking about my sketchbook in terms of "how" instead of "what": I pick a medium or color palette I want to experiment with or improve at and dedicate the entire spread to that. It's helped me avoid succumbing to perfectionism-induced decision paralysis because I just think about cool stuff I want to try instead of getting stuck on making a pretty picture.
I always mix my own paint colors as a rule — I've owned only cyan, magenta, and yellow (plus black and white) for years — but I've been really into nontraditional primaries lately. It's an interesting challenge that produces interesting paintings, and the Zorn palette is a particularly... limiting limited palette.
The Zorn palette is named for Anders Zorn, a Swedish painter who used it extensively in his work. It consists of cadmium red light, yellow ochre, ivory black, and titanium white, a color selection that locks you out of blue and most shades of green. If you're using the Zorn palette for portraits, this isn't a major limitation, but landscapes are a different story (and guess what I've been using it for)...
I love tiny palettes. They're the type of thing that I see and swear I'm going to do [x] (paint) more because I have [y] (a tiny paint palette). I thought really hard about getting a fancy small wooden palette (as seen in this tiny palette mega review by Leslie Stroz), but decided against it in favor of engineering one out of a mint tin. I also love putting random shit in mint tins. I already keep my small cross stitching projects in one (you would be shocked at the amount of embroidery floss you can stuff into one Altoids tin).
