Once the area on top of the table is basted, I move the quilt one way or another, binder clip and baste as described. Typically I don't have to use binder clips on the part that is already basted. Its weight holds that side of the quilt in place. I just flip the batting and top up so the backing is visible, binder clip backing to the table so the backing is firmly in position but not stretched and then lay the rest of the sandwich back down to be basted.
