Top layer is bumpy and never goes near the iron draw the she on the s,ooth side and cut out.put bumpy side on shape fabric back and press into place.
Now peel off the smooth white backing. It will come.It is white fits very snugly but needs peeling off gently. To fuse press on and hold still for 10 seconds works best for me and not ironing.
Hope this makes sense if not someone else will be along soon.
