Abstract
A fabric hammock provides storage for feeding a batting layer into a quilting frame. Compared to a conventional supply roll wound onto a roller, the hammock is easily loaded and automatically maintains constant low tension while feeding the batting material to the quilting frame. Compared to a conventional arrangement allowing the batting material to hang down to the floor, the hammock keeps the batting material off the floor and out from underfoot.
