Thanks! Quilting is the only thing I've attempted where being a perfectionist is a definite asset!
I lost between a quarter and half an inch on the Duck and Ducklings block and it's not as square as I'd like, but it's close. Ohio Star was easier to keep square, but it's off by a little too, so we'll see how the next four turn out. If I'm consistently off the blocks will still be comparatively accurate, I figure. :)
