Last week I experimented with limiting my tools to just a few Daniel Smith watercolor sticks, and a bit of pen and ink. (The subject, fortunately, was a study in colors and tones that happened to match the sticks I own.) I am fairly pleased with the result, and I must say that the sticks are easy to use. I mostly just dabbed a wet brush on the end of one and worked from there. I tried drawing with them a bit, but since the sticks are not sharpened to a point, I preferred working with ink pens to achieve finer lines.
(My friend Rita has cut sticks and placed them in tiny pans inside an Altoid tin for her travel set, which is very clever indeed!)
