For those of you who don't know what a Magic Pinwheel is: http://www.quiltingboard.com/t-57130-1.htm
So I'm making mine. I have my charm squares sewn together and bordered. I'm getting ready to cut with my 3.5" ruler. When I saw this demo-ed, the lady used one of those tiny Olfa rotary cutters. I have a 45 mm. So I'm wondering, for those of you who have made one, does it matter if I'm using my regular 45 mm or should I get smaller rotary cutter?
I could see it being a little easier with the tiny cutter, but I'm wondering if it goes into the "you must have" or "slightly easier but no big deal" category. Like when I was learning how to make something out of Perler beads and I asked if I had to have the peg board and everyone said "get the pegboard!"
