I sandwich my quilts, big and small to the carpet in my family room. I use gorilla tape and tape in a few spots, I have found I get less creases if I do not pull the backing fabric very tightly. I just lay it out flat, smooth out the wrinkles then lay the batting on, fold the batting back half way and start spray basting, smooth that out. Finally add the quilt top and do the same as I did with the batting. One thing I do try to spray the batting and not the fabric, but sometimes I have had to spray the fabric, just so I know it sticks. Occasionally I safety pin it here and there. It works for me. Now the carpet is a very low nap one and the tape sticks very well to it.
