Today I learned something that I should have known previously. I talked about my rotary cutter earlier this month here. So far I have been using it to cut through only one piece of material at a time. My mother-in-law mentioned today how nice it cuts through a stack of material. I hadn't even thought of trying this. Tonight I did. I used the rotary cutter to cut through eight layers of material. It cut through all eight like butter! I loved this tool already but now I like it even more. I can cut things out so quickly and with such accuracy. I love it!
