Welcome from Texas!
I don't know beans about batting, but it's interesting to know that something like that in earlier times was considered worth conserving. These days the postage to send it back to be re-carded would outweigh the value, possibly. I have a wild hunch that some quilting history museum might be interested in it. I never knew about this process of maintaining wool batting, and it seems like information that should be noted, especially because the process of getting it out of the quilt and then back in and retying it later involved quite a lot of labor - more woman's work that I never even knew about.
