Hi from fellow Michigander!! I'm down in the Belleville area (not far from Ann Arbor). I just ran across a Facebook group who is doing the same thing. She's selling off 40+ years of her mom's fabrics who can no longer sew (from what I read). Anyway, she set up the group - took pics with the yardage and the price - also laid a measuring tape on the fabric for scale. She ran it all day yesterday and shipping out twice a week. She'll be listing more in a few days.
here's the link --

Then, what you don't end up selling, you could donate.
Good Luck !!
