Nann suggested removing the borders and moving the blocks back to their original positions. I liked the idea of just removing the borders and sort of starting over, so that’s what I did.
The interesting thing is that this quilt was square without any effort. I hadn’t thought of quilt-as-you-go (QAYG) as a good way to get a square quilt, but apparently it was in this case, at least!
