Judy, how big is your quilt?
I use %)% basting spray and it works great.
You can tape the bottom of your quilt to the floor, with masking or painters tape works really well. Then spray, then batting on this , making sure it is smooth, and tape it down also, then more spray. Then the top making sure it is also smooth. If it is a big piece, you can then pin it with safety pins. When you start quilting, start in the middle, and if you come up to a
place that is puckering, you can smooth it to the outside. I hope this helps!
