I have a small house and not much space either of wall or floor or furniture for that matter. I do a lot of layout on top of our queen bed, it may be hard on the back but it's easier than the floor! Currently I use an old cutting mat that I slide under the part of the quilt I need to pin. Then as I go along I just move the cutting board. It seems to work well for me. On a large quilt like the one in the picture I only work for 30 minutes or so and then stand up to rest my back and attend to another chore and then come back later.
