I have a HandiQuilter Avante. My dealer invented the Zip Quick Leader System and I love it! The cloth leaders are attached to the bars with heavy Velcro. There are separating zippers sewn to each leader. You unzip and pin the unzipped part of the zipper to the top and bottom of the backing and the bottom of the top, then zip it back onto the leaders. The batting is floated. Sue and her daughter, Angie, are the owners of Quilting Connections in Elkhorn, WI. Very nice and helpful people. You can contact them and ask if the Zip Quick will work for your frame.
