I absolutely prefer my fabric to be ripped. It's unbelievable how off grain some places cut the fabric, and if you don't want screwy squares, you want them on the straight grain. Don't talk to me about how much fabric is lost when having to cut off the little bit of edge when a piece is ripped. There's not anywhere near as much fabric lost that way than is lost when the fabric is cut wierd. When I have to have strips etc, I always rip it because I never get it cut straight, and neither does anyone else, I think.
