The ruler and cutting edge don't measure to the right size. My favorite quilt store uses this cutter to cute for their quilts and she didn't realize it until I pointed it out. She has been giving away lots of extra inches to customers. I can't find any way to figure out how to solve this so if you can help me I would be very grateful. Thank you for being there.
