I started making quilts before rotary cutters were invented. Don't laugh - it's true. Since then, I have acquired a small collection of them. This is the one that I use the most at present - the wonderful Olfa 28mm cutter. With this, I cut all the pieces for the Feathered Star quilt I showed earlier in the week.
Sadly, rotary cutters do not cut through metal pins. Funny, that. My cutter acquired a tiny, tiny nick (I need to put on my specs to see it), which necessitated a trip to the shop for a new blade. Now I'm cutting like a wild woman again.
