I am one that doesn't use the specialty rulers. I have my 6 and 12 inch square up rulers, and my 24 x 5 for cutting lengths. I do have a 60' triangle b/c I use it alot. This year I was playing around w/ the dresdens in the Boom swap so I splurged and got a dresden ruler, but most of the time I just used my protractor and some freezer paper b/c the dresden only worked for the one angle (I can't remember which one I got maybe the 20 blade) but I wanted to make 10, 12, 16, 24 bladed dressies so that one ruler was useless for the other sizes.
