In a moment of temporary insanity, I decided to make a queen sized quilt made entirely of half-square triangles, 1-1/2 finished size-over 1,400 of them. Eight rows to the block, with the top four mirror image of the bottom four so it seems like each row is different. I calculated how many packages of Thangles I would need, and plunked down my credit card. Worth every penny to have each one come out perfectly sized!
