I find that if you're working on a quilt that has basis edges, to starch the heck out of the fabric beforehand. I'm working on a Smith Mountain by Bonnie Hunter and I didn't starch any of it and am regretting it greatly. Won't make that mistake again. Also someone gave me the suggestion once when I found I had stretched my quilt when I it was on the frame to steam it and that should get rid of some if not all the extra fabric. I tried it and it worked like a charm for me.
