This is hands down the best shape cutting system on the market. I am severely craft knife challenged, so I had to find a system with a cutter -- I tried them all and it wasn't until I tried this one that I knew I had found the answer!!! I'm gonna run go PM the other reviewers about the size -- you can put the cutter in backwards and cut around the outside to make bigger and bigger circles -- just to be sure -- I just now cut one over 12" in diameter!!!!!!!! Run to buy this one ladies -- I can't wait for them to come out with a rectangle for mats!!!!!
