I crochet rugs from coth that I don't know what else to do with it. cut from selvage to selvage 1 1/4 in. sew ends together making a long strip and fold in half making a ball.If it is cotton, you do not have to iron it as it will stay folded when it is made into a ball. Then crochet it into a rug. You will never know what it is in a rug.
That is what I would do with it. Good luck
