The product I have used over and over, and is adored by everyone who has received a quilt backed with it, is advertised as Minky Cuddle by Shannon Fabrics. It is 100% polyester and washes and dries like a dream. When I have had it long armed on larger quilts, my quilter said she has had no problem with it. When I make smaller children's quilts, I glue baste it with Elmer's School Glue and quilt it myself. I have never had so much as a wrinkle in the backing. I purchase it at quiltedtreasures.net, and it costs about $18 per yard. It is 60" wide. It comes in a huge variety of colors from black to the palest pink. They even carry a zebra print. I have never used any other brand, so I can't speak to them, but this fabric is fantastic. If you live in the Minneapolis area, the Quilted Treasures shop is in Rogers. I do not work for them. I'm just a very satisfied customer.
