A friend gave me all her mom's heavy polyester slacks after she passed away. I made a quilt of simple squares and gave it back to her as a memorial to her mom. She was very touched, but complained that every time her husband worked out in winter weather HE was the one who grabbed it and wrapped up in it to get warm. I also "inherited" several boxes of polyester 3" squares. I put them together as attractively as I could and made large blocks out of them. Made my grandson a double sized quilt he could drag around in his car for graduation. He loves it. Says it is the warmest thing in the house. He also knows that it is okay to take to the beach, use in the car, throw out for a picnic, or whatever and grandma won't be upset about it if she finds out! Well worth using that fabric!
