1. Draw a ground line and the center tree trunk with a pencil. Add curly branches to the left and right. Add more curls wherever they fit.
2. Trace all the pencil lines with a chisel-tip black Sharpie marker. Add some extra thickness to the tree trunk and beginning of the branches.
3. Paint the ground one color (I love Dick Blick Liquid Watercolor paints). Paint splotches of color all over the tree and background. Overlap the splotches a bit so that the colors run together.
