I glue baste with washable school glue squiggled on in a thin stream. This can be done in sections on any size surface. I put the batting down then lay the back or top over that to position. I then fold the top/back back and squiggle the glue on the batting. Since the batting is heavier than fabric there is no clamping down. There are also no wrinkles in the top/back since you are smoothing that over the glued batting with your hand. You don't need a large surface that will be the size of the whole quilt using this method.
