I've made two footprints for my tents - one B/C it didn't have one, the other B/C the original was made from material that was way too heavy.

In both cases I added elastic loops at the corners to loop over the tent stake-out tabs. This keeps high winds from blowing the footprint away under the tent. (Happens!) Of course you have to hem the edges so no raw material edge is showing. A very narrow hem is fine, just be sure you're sweing through 3 thicknesses of fabric, not two.

**When cutting the footprint shape raw cut make it about 1 1/2 inches SMALLER than the tent floor size. Then it will be about 2 inches smaller when hemmed. This keeps water from rolling off the tent & on top of the footprint.

** FABRIC: This is up to you. Urethane coated ripstop nylon is tough. HEAVILY silicon coated silnylon, like TarpTent uses for its floors, is good too, just a bit more money for the lighter weight.

Don't forget the corner loops.
