On making my own covers and I'm sure many of you know that wrapping the cushions with batting is a must. From YouTube we learned how to put the cushions into the cover without a hassle. Bag it, use vacuum to suck the air out which shrinks the foam, place in cover, release, and tear the bag out. Makes it so easy.
