Okay, time to play with layout. I have to think about this carefully, from these I have to build all the pinwheel blocks, and each one is different! They all have little triangles of the next block built into them so there is no going back. I didn’t think of that when I started. There’s a lot more to the Tilt-A-Whirl pattern than I ever realized.
Blocks and triangles assembled in strips. There are a few points to match in here! Scrappy border started. I need a bigger design wall!
