My way is probably not the most desirable to most people but I will gladly share my methods... I have hardwood floors, so I lay my backing down and use masking tape to keep it secure and taut (not stretched). Then spray the backing, roll out the batting, spray again, then roll out the top. I use a 4 ft. long, 1" wooden dowell to smooth each layer before spraying, which works great & saves the back & knees. (this is a trick I learned while working in a uniform manufacturing company spreading out the fabric for the pieces to be cut from) If it is a quilt larger than a full size, I will pin baste in addition to the spray because it takes me more than a couple of weeks to complete the quilting. On a full or smaller I just use the spray.
