I'm trying the glue because I can buy a big bottle of glue for a dollar....spray basting is messy (overspray), expensive, and I can put the glue on the batting, allowing me to see the backing/top and smooth away any wrinkles before the glue dries. I've already done the top and am thrilled with how easily it works, the backing is half done and is 100% smooth! It does take a bit longer, but well worth the effort. For those of you who iron the glue dry, are you spreading your quilt on the floor to iron? what are you putting underneath to protect the surface? I have currently spread my quilt out on the pool table and doing about 1/3 at a time, but no ironing there....hubby would disown me
