just like fusable applique you still have to stitch them down after fusing them. press the iron on patch over the hole very well, it takes a HOT iron. then let it cool completely and stitch a zig-zag stitch around the patch. you can also put appliques over the hole, use the iron on patch on the inside and an applique of some sort on the outside. double the thickness then and hopefully will hold up a little longer.
