Thanks for the compliments.
Whitepine: I only save my bigger corners. On this one, I cut triangles and lined them up on the corners and left the backing fabric. The two fabrics weren't bulky so I could leave them. When I made the 4 extra blocks, I actually oversized my triangles and trimmed them with a Deb Tucker ruler. They trimmed down to the correct size so nicely since they were a little bigger than my previous method. I love learning new techniques.
