I don't think this has been mentioned but it's very important. If your cutting a piece of fabric 4 inches wide then every fourth cut you have to re straighten the edge. 6 inch width cut, re straighten every sixth cut and so forth. At least check to see if it is exactly straight after every few cuts. I always had to re cut to get a straight edge after cutting a few strips. I bought the Go because I was tired of spending time cutting and being frustrated and making it work anyway.
