This hasn't changed much since I last posted it, but the palette is #4. or #5. I've lost track! I must also give credit to timoliver1959 for the idea of using a pencil case. This is still (for me) the most practical way to carry art supplies. Thanks Tim!
watercolor journaling sketchbook - Google Search...Nice little watercolor palettes. I bought one a while back from Wet Paint Art, but I don't think they sell them there anymore. They are so cool. The pans are 1/4 pans and you can fit a Sakura Koi water brush separated in the middle. Totally fits in the purse.
