Last weekend at guild we had a great lesson on piecing curves presented by Alvina. She had a couple of gorgeous quilts to show that were completed done with these blocks with the curved seam. And she gave each of us a baggie with these pieces already cut so we could take them home and try out the technique.
My results - which I think will become a pillow since it is 14.5" square. Hopefully my stash has a light blue to match those little circles.
