One thing I learned in covering my test frames is that my relatively large workbenchwas going to feel on the small side when coving full sized parts. The other thing I worry about is getting the covering dirty on my bare concrete floor.
To make life a little eaiser for myself I set a 4 x 8 peice of melanine on sawhorses for a makeshift table, and then I built a quick rack to hold the covering material so I can control it when cutting off what I need, and keep it up off the floor.
