I had a lot of fun with this project!  I did several versions in a couple of different sizes and colors.  I used watercolors, alcohol markers, acrylic paint markers, glitter pens and chalk pastel pencils so that each one has a different look.  I even emboridered the one I did in the color wheel with some silver thread, which was a lot of fun.  Just for something different, I tried outlining the purple one with the gold freehand, but I think I will stick to using the ruler and compass from this point.
