I usually paint in oils, but when I'm traveling, as I am this week, I grab my watercolors and gouache. I'm taking a watercolor sketch book, as usual, but I may also bring a couple of Ampersand Aquabord panels. I'm still debating about whether they're worth the added weight.
On the one hand, there's an irrational part of me that seems to concentrate more when painting on a rigid support. It's as if a panel is Art, and paper is a mere sketch. On the other hand, there's a very rational part of me (my hernia scar!) that prefers to travel very light, which argues for paper. Plus, we all know from "rock paper scissors" that paper covers masonite, not the other way around. (Ha!)
Anyway, if I produce anything of note, I'll post it in this space. At the very least, I hope to attend a figure-drawing session, so I may have a few gesture drawings to show off.
