I don't find on-point quilts any more difficult to make than any other quilt. Except for figuring out the sides and corners! I'm out of town currently, but I have site bookmarked with how to calculate those pieces. I know I picked up the original link from here somewhere so perhaps doing an advanced search here for 'on point quilts' or something along those lines will reveal the link for you. And I only use regular rulers. The corners and sides are usually just large squares of fabric cut diagonally twice. And certainly second the comment about making them larger.
