I was given some polyster/cotton. I used it as it was the most beautiful shade of blue. My friend returned the pillow sham for repair as the fabric did not hold up. (replaced the blue with cotton) I made a quilt our of polycotton which I gave to my daughter. After much use and washings she asked me if it could be repaired. This is what I have run into, Take your chances. I'll stick to cotton.
