I just spray basted a queen size quilt and it was fast and easy. I also use a table doing it one half at a time.
I use 505 and it works and holds beautifully....you don't even need to use a lot. Spray(quickly and lightly)your backing, lay down the batting, spray the batting, then lay down your quilt top. Then I slide the whole quilt over and repeat the process for the other half. It does help considerably if you have someone that can stand at the other end of the table from you to assist in laying it out and smoothing it as you go.
Good Luck!
