Watercolor is such a nice medium... It travels well, and lends itself to contemplative moments during the process. I like it because you have to be patient to build up your colors, and your darks. So it's an excuse to be too busy to help in the kitchen, but not too busy to pay attention.
This is one of my mom's trees, painted the winter of 2005! I understand she has one up today that is being decorated by my niece and nephew as I type this!
