I have decided to continue on with the pattern I showed yesterday. I did make a sample pinwheel block, which I really liked, but I made it the wrong size! For some reason I thought I needed a 4.5-inch block, when I really needed a 6-inch. I was too frustrated to make a bigger one and just decided to go with what I had originally planned.
Those who commented said they thought the pattern worked nicely and I agree. You can see the pinwheel block sitting alone. I like it, but I think I like the other better. If I feel very ambitious, I may make chair backs with the pinwheel blocks....maybe.....that's a lot of work.
I have no ideas yet how I will finish the ends. I never know until I get to that point.
