Well, for me, I can't bend over on the floor let alone get back up. So I currently use my dining table. I tape down a section at a time and pin. then I lay it on carpet in the living room to make sure it's straight.
I'm going to make a plywood top for the table, though, so I can do the whole thing at once, or half, at least! Got my plan all ready, just need some good weather to go outside to cut.
