I have started this quilt but haven't needed any specialty rulers. Just a long ruler to cut strips, a shorter ruler to cut smaller pieces, and a square up ruler. I did paper foundation piece a lot of my blocks though which would be difficult by hand. The blocks are old patterns and back then only a ruler for measuring, paper and pencil for templates and scissors were used. I plan on putting it together QAYG with sashing when I get the rest of the blocks done.
