My LQS owner owns a Gingher rotary cutter and cut a layer cake into 5" squares for me in less than 2 minutes. She told me to forget the cutter but to buy the blade. So I did. I love it. I can cut so many layers of fabric with it. I think it cost $12. I absolutely love it. She said she's used the same one for 9 months at her store. Awesome!!!!
