I have only been quilting 5 years but have churned out 112 quilts & #113 is almost done and they are all nice sized quilts, only 2 wall hangings. I only pinned the first 3 or 4 quilts and have been spraying since then. I do not bother to pin once it's sprayed. Any of the brands are satisfactory, some are stickier than others (like Sullivan's in the pink can), June Taylor's is just as good as any. Use sparingly until you learn it's properties. The fumes can be daunting but good ventilation helps a lot, however, do not put a fan on your work. I have a king size bed that I cover with a big flannel sheet and do the layering on that. I have bad knees and do not crawl around on the floor. The flannel sheet holds my work firmly and helps protect the work area. Lay batting down, position backing, peel backing back half way, spray batting, and smooth backing down, peel back other half and repeat. Flip over, position top, and repeat process. Anyone need a big box of pins?
