I've also had this problem lately with a aqua polka dot 108 backing from Missouri Star. It's an absolutely terrible piece of fabric. Unfortunately spray starch didn't help at all. I wrote to them telling them of my disfaction and of course they want a boat load of photo's before deciding on giving me credit or not. The only thing I can think to do is to cut all borders at least an inch larger than I need and then sewing with a much wider seam so it doesn't ravel near the edge. Not the best solution, but it may be better than throwing in the trash.
