Spray starch helps a lot, especially any piece with a bias (starch before cutting) and the backs of quilts to be machine quilted. I hope you find a good source in your area. If not, it can be ordered online. It would be costly, but if you have a guild or just several quilting friends, you might be able to get together on a larger quantity to share. Maybe it would be reasonable. Amazon, for one, lists a large number of brands, so they must be reasonable enough to attract some buyers. Another idea: possibly a local laundry service could get some for you? That's just a guess, but there would be nothing to lose by asking.
