I recently got a question in the comments section of my post about getting straight cuts on large pieces of fabric. Amanda asked, “When I fold a larger piece of fabric in order to cut it, even though I’ve lined it up and squared it off, when I open the fabric up, sometimes I find the cut is curved. I used a rotary cutter and mat and ruler, but I can not figure out why this happens quite often. What do you think the problem is?”
