I buy on the roll also. I cut what I need and spread it out on my dining room table with a vinyl padded tablecloth underneath it. I fill my 400 hole steam iron, hold the iron about 4-6 inches away from the batting, and hit it with a shot of steam. Like magic, the batting puffs up and the wrinkles are removed. I move the iron along the whole piece until wrinkles are gone, never touching the batting with the iron itself. It's fast and produces great results. I leave the batting sit on the table to make sure any moisture is dried from it before I place my quilt top and backing on it.
