I bought the border fabric for the BOM I finally finished. The instructions say to cut the fabric lengthwise. This is the largest quilt I have made so far, so I've never had a border this long before. I've always cut from selvage to selvage and then pieced them together to get the length I want. I'm just afraid that if I cut the fabric lengthwise that I will end up with a zigzagged cut (from not folding the fabric straight). I read in another post about ripping the fabric, I've never done that before, can you rip it lengthwise? I'm a little afraid about ripping this fabric, it was pretty expensive. Help - I'm confused!! :(
