Dependng on the size of the quilt I either do it on a table or on the floor. Like others, I stretch my backing taut, but not too much as to stretch it. On the table I use clips to hold the backing. On the floor I use painters tape. Lay on the batting, then the top. I pin baste about every 4 or 5 inches. When done I always check the back first before going any farther. Make any corrections as needed, then quilt til your hearts content. I've never had a problem with pleats, folds, or creases. Good luck. Oh, I would like to try the basting spray. Just haven't yet.
