I always use Elmer's School Glue for basting. It holds the "minky" backing without any stretching at all. I always use batting also. I have had one quilt where I used a Jo-Ann "minky" that had longer plush, and it did pull through to the top. I tore it off and used a different backing. I've also used a dimpled "minky" that wouldn't adhere to the glue, so I did have to spray baste that one. Now I won't use any "minky" except Shannon Cuddle. Never any problems.
