Anyone make a clam shell quilt?

[Hulamoon]

I'm trying to think of a design for the shop from your stash group. I have a magizene that has a template and you make a cardstock template. Then you iron The edges over it, and sew by machine. Then online there is paper pieced directions and you sew by hand like a hexi.

Any experience with this pattern? I thought it would be cute in all the kids prints I have.

This is interesting the link shows the machine way sewing the curve together in sections. My mag has it in whole pieces and sewn to a strip of fabric. .
