I've been using this notion called Leadergrips. It holds backing fabric on the leaders of the quilt frame without pins or staples or velcro. The web site www.leadergrips.com tells about the item and there is a u tube to watch how it is set up. There is free shipping till the end of January 2011. Was seen at the MQX and Quilting with Machines in Ohio this past year. Load a quilt in less than 10 minutes and getting to the fun part of quilting--quilting.
