What to Do with Antique Yarn?

OK that guy was not kidding. The yarn is from the early 1900's, Brehm & Stehle Textile Co out of PA. They made yarn for rugs. Some of it is too old to use, but I think most of it just needs a good airing out.
I am planning on going to a KIP in protest of the greedy silverback who wants to tear down the Magnolia tree. This is planned for Mon 4-6 and I'm hauling a lot of the yarn with me to give away. Yay!
