I don't remember what year it was when I first learned about rotary cutters. Maybe I saw them demonstrated on TV...but I was impressed and wanted to get one. Went to the local fabric store (I think it was called House of fabrics). I tried to describe the cutters but couldn't recall what they were called. So I told the sales lady it is like a pizza cutter, but made for cutting fabric. She was flabbergasted, never heard of such a thing!
It was quite a while before I could get one, but worth the wait!
