I do the same but use batting tape I buy by the 100 yards roll. I try to order the same type of batting but once I tried Hobbs so have some scraps from it. I'll also never buy it again. I normally used QD 70/30 or maybe it's 80/20 but I like it much better. Any scrap too small to piece together I'll use either for embroidery designs or I'll cut them into 3x3 inch pieces to use with alcohol to clean my quilt frame rails so not much gets tossed into the trash can these days.. They're also great to dust with too.
