White watercolor paper. I had them trace a 6" circle at the top, center of paper. Water color wash any type of sky, leaving the moon white. Then black india ink with a wide flat 1" brush. I showed them how to go from thick to thin, twisting the brush slowly, (I suggest a practice paper first for 2 minutes). Then magenta, white and purple for the blossoms with a #4 round. 5th grade.
