I saw the show as well and that quilt was stunning! I loved the secondary ring pattern the blocks made. Shoo Fly is very easy but the 54-40 or Die really isn't. I don't normally purchase rulers that can only be used in certain circumstances. I speed piece all my HST so I've not ever needed a special ruler for those and I prefer to sew on the bias before cutting, but I dont' think those weird Isosiles triangle things can be pieced that way. I'm seriously considering purchasing those triangle rulers. I really love that pattern and put it on my to do list. I've never seen any rulers that aren't F&P rulers promoted on the show before.
