I recently had a quilt where many of the blocks AND the inner border were, shall we say generously proportioned. They really puffed up a lot. I ordered the tape measure that Cindi recommended in the above post, but before it arrived, I used a piece of twill tape (doesn't stretch) and some of those spring type hair clips and was able to keep the quilt mostly in square. The measurements on the ruler are ideal, but my substitute did work for the quilt I had on the frame.
