Mamaduck: I can describe how mine works. First you need to attach strips of fabric to the long sides. Some sturdy fabric like canvas. You can either staple it or make a sleeve that can slips on the bars. Attach the back to the strips on both sides using safety pins or a long running stitch. Then just roll the back on one of the bars until the back is taught. Place the batting on the back putting the excess even on all sides including the side attached to the bar. Using either spray adhesive or glue attach adhere. As you get one section adhered wind the unloaded bar to the next section. Do the same with the top. Remove and quilt. Hope this helps.
