I used to use binder clips but since I have been glue basting I don't need to hold anything down. I put the quilt bat down first and that pretty much stays in place. I squiggle the thin stream of glue on the batting and then smooth the back down over that with my hands and let it dry. I do it in sections. When the back is dry I flip it over, squiggle some thin streams of glue on the batting and smooth the top over that. No stretching from using the clips too tight and no wrinkles in my backing or top.
