When I'm at home in Alberta I live in a lake cabin so I don't have a lot of floor area to lay out a large quilt so I bought a folding table. When it's time to sandwich a quilt I lay as much of the backing on the table as will fit & use large clips that I purchased at the hardware store to get the backing taut, next the batting & then the quilt top. I use curved safety pins to secure the layers. When one section is pinned I move the next section on to the table & proceed to sandwich that. I have tried spray basting but don't like the fumes.
