I just read the link provided above and noticed one turn off for me... You have to wait to let the glue/paste dry overnight or iron it dry. Usually once I spray baste I go right to the sewing machine. No way do I want to wait over night for it to dry- and I do enough ironing as I make the blocks and then prepare it for sandwiching. I'd rather pay more and use less effort. Yes, its cheaper than the commercial spray, but a can will do several quilts and costs less than one yard of fabric. And my time and effort are surely worth something. After considering everything it sounds penny wise and pound foolish to me. But that's just my thoughts. To each his own.
