I've posted my problem with this before. Unless I put the metal gauge in the exact same place on the fabric every time I cut I get cuts that are not exact from one cut to the next. If the bottom of the fabric is not lined up perfectly exactly straight on the mat line I get the V when cutting strips. I was spending more time getting the fabric in place and lining up the gauge to the exact spot it was taking me a long time to make one cut. What am I doing wrong?
