I pin baste my quilts. I also tried glue but couldn't get smooth either. I first lay my quilts on the floor and put the backing, batting and top together, then along with hubby's help I move the whole thing to my dining table which opens up to 125". Start pinning in the middle and smooth and pin my way out to the edges. When I FMQ it, I also start in the middle and work out to the sides. Then if needed I may repin if there is any puckers, etc. Works for me.
