I'm an Elmer's fan through and through!!! I have convinced several of my quild buddies and we would never go back to pins or spray. I thin very slightly with water and apply with the Elmer's squeeze bottle in a grid an then us a damp sponge brush to smooth it out. I heat set with a medium iron (even poly) and pile them up on the futon in my guest room. It may be several months before I get to the bottom of the pile and I have never had puckers, pleats, or a problem with my sweet 16 quilting it. I usually baste 6 or 7 at time. Most of my quilts are for charity.
