I'm for using large tables. The library allows me to occupy a conference room, and there are 4 large tables to scoot together. I can't do the floor dance anymore, it kills my knees. I don't have any clamps, and usually forget my tape but there are shelves and shelves of reference books I use to weight down one end. Because I can't use spray adhesive in the public room, I pin, starting in the center going out towards the edges.
