If your upholsterer is using wool batting, there is no need for glue, since wool will stick naturally to the foam. You don’t need to glue it to the foam, but you do need to wrap it to hold the wool in place as you stuff it into the cushion cover. Our Premium Wool Batting comes with a thin spun backing, which is perfect for this purpose. You can either hand stitch or staple it around the edges. Remember that when you use wool batting, you’ll need a ‘ticking’ layer (a tight-weave organic cotton fabric) between the batting and the outer upholstery fabric to keep the wool fibers from migrating through the cover fabric (exceptions are leather and other non-woven covers).
