Do I cut the batting and the backing the same size as the front of the quilt before I machine quilt my quilt? It seems like I should so that everything will line up properly. I'm going to use 505 basting spray. I'll apply it in my garage with the door open. Do I apply it liberally? Do I let it sit for so long? Like a half an hour? I usually take my quilts to a LAQ. This is my first attempt at trying to do it myself and am hoping everything goes well so I can start quilting for now on and save me money. I am going to quilt 1/4" next to each seam. Any tips will be greatly appreciated.
