A clamshell cushion

I recently made some Christmas presents, and decided to try English paper-piecing in a clamshell pattern, which was pretty tricky. Here is the method I perfected, as projects go it was a bit too┬átime consuming, even for me. The result was really pretty but a medium sized cushion took A LOT of work – it was a lovely present for my mother-in-law, but not one I think I’ll repeat soon.
