There is also Heirloom 80/20 Fusible batting. You iron it on both sides at the same time. If you get a wrinkle just pull it up and repress. Once you wash the quilt the chemicals that are used for the fusible part washes away.
I've not used it, just heard about it at the Knoxville show. It's by Hobbs. I may carry it once my shop is open. I don't have prices on it yet.
