The challenge this week is to use color, any kind of color you choose! I had not made a mandala from scratch lately, so I made that my challenge along with the color. Instead of doing a lot of tangling on it, I concentrated on the color. I used a piece of tan paper (I can't tell you what kind, because someone gave me a few sheets awhile back) and then used my Prismacolor pencils to practice blending and shading. When I was done I used some Sakura gelly roll pens to tangle and highlight on top of the pencil.
