I have a fairly cheap 2 man 3 season tent with lots of happy memories and a worn out floor. Even without rain, condensation from grass comes up through the floor and gets stuff damp. The thought suddenly occurred that getting a footprint/groundsheet (tyvek, perhaps) might avoid this problem and extend the tent's life a bit.
So, questions:
1) Does this work? Is it a bad idea?
2) How do you obtain a footprint of the right size?
The tent is an older, but pretty much identical, version of this:
