I have a small house LSM52, and most of the walls have openings of some sort, the only possible wall I have is the hallway and since I can't stand back from it, sort of takes that out of the equation.
The only place I could figure out is the back of my sewing room door, not ideal, but enough to put up sections and get some perspective. Easy enough to attach some flannel or something.
Other than that, my layout space is the queen sized bed -- and the hubby does object to me draping fabric over him so I have to wait until he goes to work... I take pictures and number blocks with alpha/numeric paper labels held on with safety pins. It's amazing the things you can pick out in a photograph that you don't see live and in person. I have a roll of heavy kraft (brown paper, like the old school paper bags were made of), I cut off 3 sections that I overlap to cover the bed and I use them until they get gross with spray baste or just get too soft to use. Then I cut new ones, the currently used ones I just coil around the outside of the roll for storage, but it's in the bedroom because I use it almost every day.
