Here's my tiny DYI Altoid's set with six colors, water brush, and one #8 round watercolor brush. I used my official sketchbook (rebound with Fabriano 140#CP) which will be for the 2015 Sketchbook Project. In addition I used a Micron pen, sponge, a small #4 round travel brush and a pencil.
Both sketches on this spread were done with just those tools.
2. I started thinking about how close I was to a fire hydrant in an area where people walk their dogs. (Hmm. It's cute, though. Maybe I'll sketch it.)
