I just used up the backing from t-shirts to make dog beds. The fronts were used in a t-shirt quilt and I have a hard time throwing anything fabric away. I put two together, stitched around 3 sides, filled it with small scraps (no thread) and serged up the sides. My small quilt group helped me last meeting and we made 15 beds. Everything from the outside to the stuffing were things that were destined for the garbage. My local shelter loves them. The only thing they request is no reused dog beds. If another dog has slept on it, they don't want it.(I bet they get shredded! My dogs would do that! lolol)
