First, I love the quilting you did on that T-shirt quilt. Makes the whole thing look fabulous! I've made 2 Tshirt quilts and they didn't look nearly as nice. Anyway, I used the leftover T-shirt/sweatshirt fabric to make small toys. Rugs are not something we've ever used due to tripping hazard for disabled family members. If you have already made them into strips, other than rugs and placemats, I can't think of what else you could make with them.
