I've used it on wall hangings for many years and have also started using raw edge applique on quilts. I recently finished a full size quilt for our DGD last Christmas (she loved it by the way), and I had flowers, hearts, butterflies and dragonflies on the quilt using raw edge applique. I finished it at 5 PM Christmas Eve and we were supposed to be at my son's by then, but I had to finish the binding first. My son grabbed the quilt as soon as we walked in the door (it was hidden in a black trash bag just to be on the safe side, he put it in the washer and then the dryer - it looked great. Since I used a fairly small straight stitch along with some small zig-zag stitches, I think it should hold up, especially since the appliques were put on using Wonder Under, so I think the appliques were fairly sturdy.
