Perhaps some of you have had to do this same thing, I'm hoping I can benefit from your experience!
My sweet MIL just passed away a month ago.. She was a professional seamstress and also managed a So-Fro Fabrics for years.. You can only guess at the amount of fabric she has in her house. The cotton yardage isn't a problem.. but the 'silkies', home-dec., canvas, double knits, single knits, corduroy, pre-quilted fabrics and every other kind of fabric you can imagine are! I don't have a clue what I can do with a hundred yards of polyester silkies and knits.
It feels wrong to toss it, it's beautiful and our land fills don't need it.. I would hate to do that, but what do I do with all this fabric that no one is wearing these days??
