Upholstery scraps are great for making oversized Floor Pillows for Children and Teenagers. I made over 100 some years ago, using a simple 5 or 6 inch square, simply sewing them together with heavy thread and a heavy duty machine needle. The filler can be foam. They were well received as gifts, and were sold out of a craft and furniture "hippy" store in town, and it turns out that the manager/owner preferred to supply the foam stuffing, which he got at a better price, so I supplied only the pillow skins.
