I cannot cut straight either I have tried everything than I descovered the June Tayler slotted ruler which helps a lot. Then one day I went to Joanns with a coupon and bought a cutting system that looks just like the cutter I use for scrapbooking. It is great I am not home so cant look for sure but I think it was made by Dewberry with coupon price wasn't bad and after a little pratice it cuts wonderful straight strips
