I am getting ready to try to work on a quilt for my brother in law. His grandmother made him a quilt years ago, and it's falling apart, and has some places that look like strings, but many more that are blocks that just need more sewing to keep them back intact again. I plan to do my best, because his grandmother along with his dad raised him. It means a lot to him. Do I just replace the few blocks that got pieces kind of ragged looking with a piece of it completely gone?
