use basting spray, no pins needed. Lay an old sheet on the floor then make your quilt sandwich making sure it's nice and flat, pull back the top layer half way, give it a light spray of the basting spray then smooth it back over the batting, do the same for the other half of the front...then pull back the batting and the top and do the same. Doesn't matter if you do the bottom first, whichever is easiest for you. Basting spray is my new best friend, I'll never pin again. Good luck
