I'm not sure what the name of the tool is, but it's a ruler that has slits at regularly spaced slots - you insert the rotary cutter and cut within those slits, it might be an Accucut ruler thing. I've seen them used, and it might help your problem. Just a suggestion. Good luck - hang in there and may go to LQS, have someone watch you cut and they may be able to figure out what you are doing wrong. Don't give up.
