After pinning my first couple of quilts, I found the basting spray as well. I started with the cheaper ones, not too much trouble with gumming up the needle but cleaning up the over-spray and had a hard time getting the sticky stuff off my fingers. I use the 505 spray now, smells better, cleans up nicer but more expensive. I have probably spray-basted 35 or more quilts. Make sure that you don't use too much spray and I like to put old sheets and stuff around the edges so I don't get spray on the floor (or tables,or wherever)
