Several years ago, I bought a pattern using yo-yo's. It was a 6 inch octagon shaped block (I used white on white for the background. I appliqued three leaves on the center of the block and appliqued the yo-yo's where the leaves intersected. It made a flower. Then sewed the blocks to together using half background blocks to make it even at the sides and top. You could just blind it without the background half block but I decided not to deal the the innies and outies. The pattern called for completing each block, including the quilting, and then sewing them together. I decided to make the top and then sandwich and quilt it in the traditional manner. I am not a yo-yo fan, so even this was a big stretch for me. Good luck.
