Give it away LOL. Find a Project Linus chapter in your area, or as close to you, as you can, CALL them and tell someone you have 200 pounds of fabric (thats about 600 yards) all cottons and ask them to come get it... I bet they take you up on it with no problem. And I would presume P.Linus will give a receipt you could use at tax time, it might be a tax deduction would be worth more than $1 a yard and having strangers in your house.
I am sure your area also has nursing homes, senior centers, and churches. They would come get donated cotton s too. Good luck.
