The star blocks aren't coming together easily as the chain blocks. There has to be some trick for working with triangles I've yet to discover. One that would keep the fabric from stretching and distorting when sewing. I've cheated in the past by cutting pieces larger than necessary. Then trimming them down. But this was to be an "easy" jelly roll project, so I cut my pieces accordingly.
My LQS offers a class called "No Fear Triangles," I think I'm gonna take that class! :)
