There is a trick where you put a large marble underneath the backing which holds up the backing from the floor. You then roll the marble to the next area and pin. I have a tile floor, so this hasn't been an issue. I've also pinned them on a table using clamps. I am now trying Sharon Schambert's way of hand basting. Haven't decided if I REALLY like it or not, but at least I'm not on my knees on a tile floor.
