Thanks Woody for the youtube video! I had the ruler and just gave it away because I was using a regular rotary cutter and I tried both the 28 and 45 size with problems. Now I didn't know there is a rotary made just for an easy cut! I'm going to buy one of those plus I guess I have to get another Circle Cut. I have other types of those rulers too so it looks like the special rotary cutter will work far better then the others.
