Spoonflower.com makes 8 x 8 inch test prints when you submit a new design. I had a stack of these blocks by the time I was happy with my recently completed Dancing Circles designs.
I cut them up into 4 x 4 inch squares and picked coordinating colors from my stash of Kona® Cotton solids to make this fun baby quilt! The circles dance and I think the quilt does too!
