The correct answer is D; You cannot fuse interfacing to polyester.
Explanation:
Polyester is becoming more popular in quilting communities. Polyester does retain its shape just as well as cotton and has minimal shrinkage. The material is slinky and silky in texture and is good for quilts and clothing.
It is harder for an amateur quilter to fuse interfacing on polyester. There are now more advanced technologies to help a more seasoned quilter apply the interfacing onto polyester. Since it is harder to apply, the polyester is more expensive than other fabrics.
