It took a few days to make, but I made 5 of the 4th pinwheel block this week. It looks like a simple pattern, but there was a lot of work in making 5 of them. There are 20 half square triangles in each block, multiply that by 5 and you have 100 half square triangles that needed to be cut, marked, sewn, ironed, recut/squared, sewn, ironed, sewn, ironed, and squared, etc. I'm really happy that I finished it weeks before I need to turn it in to get the pattern for the 5th block.
I pieced four of them together like I did with the previous pinwheel blocks. Its not perfect, but that is ok.
