If you want to prolong the lifespan of your tent floor, consider making a simple, inexpensive groundsheet to prevent punctures. Tyvek, Type 1443R, is the material used to make high-tech kites and can be bought online by the yard. (If you want to reduce the stiffness of the sheet, wash it prior to using.) A good groundsheet should be one or two inches smaller than the footprint of the tent on all sides, so measure your tent floor and cut a rectangle that is two to four inches smaller than the tent dimensions so that when it’s centered underneath it will be perfect. You want a slightly smaller ground sheet than your tent size so that water falling off your tent does not pool up between the tent floor and the ground sheet. When you are ready to set up camp, stake down your tent hard to the ground so that the sheet underneath is not visible.
