Next you will need a ground sheet made of any sort of waterproof material. You can buy ground sheets from a camping store, use heavy weight plastic or builder's plastic or an old shower curtain. Your ground sheet will need to be about 2 metres x 1 metre, a little longer and wider than your sleeping bag when it is rolled out.
When you are sleeping, your ground sheet protects your sleeping bag and sleeping mat or air mattress from moisture and protect you from the cold. The warmth of your body draws the dampness up out of the ground and the underneath of the ground sheet will be quite wet in the morning even if the ground appeared dry when you laid the ground sheet down.
During the day your ground sheet will form the waterproof outer layer of your bedroll.
