I took a beginning quilting class and the instructor did not square the fabric before she cut it. She said it didn't matter if it was square or not because when you cut that first edge it's straight from the cut so you just had to make sure everything else was cut based on the first cut. But then, she also didn't have us press any of the seams. Just said she didn't feel a necessity to have to stop and press all the time. So now I have a lap quilt where the seams are all wonky and I have never bothered to sandwich it and quilt it. I think I'm going to try though because I really do love the fabric and the pattern. Geesh! How do some people qualify to teach quilting?
