When cutting strips with the Go!, I find that I have to stop once or twice while rolling the die through -- to lift up the mat and straighten the fabric. If I don't do that, I get ripples "ironed" into the strips and/or little jagged cuts here and there in the strips. This is caused by the fabric stretching as it is rolled through the machine. I get this even with fabric that is rolled through on the lengthwise grain (which has less stretch than the crosswise grain). Maybe it's user error.
Go info suggests putting a sheet of paper btw the fabric and rollers to prevent this problem. It works for me. The main thing to remember when cutting strips is to fold the fabric very carefully, so it is absolutely straight on the ends, or you will get the dreaded angles instead of nice straight strips.
