I finally made it into my craft room for some costume making. Z wants to be a rainbow, so that's what I'm working on.
My outline is six inches long and cut on the fold. A twelve inch rainbow base worked for even color distribution of about two inches each.
I'm marking from the edge of each color at the 2.25" mark to keep the colors as even as possible all the way around.
You can see the elastic rainbow straps at the top of the red. Very cute. I'm actually done with one side, but haven't yet taken any pictures. I'm thinking of adding a cloud base. It was my initial idea, but since I snipped pretty far into the green, it's become a much stronger idea.
