It depends on what you want to do with them if repaired and finished and how much time you want to put into it.
You might consider taking them apart and saving and using the good squares and discarding the bad ones. You can certainly find repro fabrics but I woud suggest fading the fabric to look like that in the qults or you might find something at the Thrift store in clothing that could be used.
But as I said above - depends on use and time.
