Polyester fabrics make very durable quilts. My MIL made quilts for my children when they were very young. They are now all in their late 40s and early 50s and we still have them. They don't get used like they once did but still get dragged out when we need extra bedding to make up beds on the floor. they also have not lost their color and look as bright as they always did. Of course some of the seams are showing their age and need some repair but that is for another day!
