I do have a stack of fabrics that have polyester in them that feel nice and are pretty. I am in a bit of a quandary about what to do with them.
Bear: find a small box, label it "polyester" and put all those pretty pieces into it. When you think you have got most of them, make a quilt. To donate if you wish. Try to use it all up, and if there is anything left, put it on the back. It will make you feel good when it's gone and someone else can be warm with it.
