Hopefully, when I sew all these bits together, the seam allowances will take up enough to allow some sashing. I calcuated it, but my track record these days is not so great with those calculations. Looking at the picture, I may have a problem. But at least pinwheels are something I can cut down if they come out oversized.
You can still see the edges of some of my tic-tac-toe blocks peaking out on the right. Still waiting for a few more to arrive, so they're hanging out waiting for inspiration.
