One of the first quilts DH and I made when we started quilting (late 70's) was a Tumbling Blocks that was made from my dressmaking scraps. We used it on the bed for the last 35 years. It got pretty ragged and whenever I had spare time between projects I would repair it.
When we moved recently, to a furnished place, I gave it to a guy I know whose wife quilts, along with some of the fabric I had cut to repair it. I just spoke to her on the phone last night, and she is repairing it and putting it in a quilt show! So there can be new life for old raggedy quilts after all!
