Someone from my quilt group gave me some fat quarters for Christmas and I bought a blade for my rotary cutter that pinks. I have been using charm packs that have pinked edges and like to work with them. So I guess it is what you get use to. I have to say the pre cuts I have gotten from Connecting threads have not been cut correctly. The last one had 2 1/2 strips and some of the strips were way off.
