I prefer to have it ripped myself. Although it looks shabby its a very small thing to straighten and it instantly shows the grain of the fabric. I loose no more fabric straightening up that raggy edge than I do finding the straight of grain myself. Some material can really be off and its frustrating to get a yard of fabric and loose several inches to it being so wonky. Do you fold your fabric selvage to selvage or with your fold hanging straight and smooth?
