If you like camping as much as I do, here are a few goods tips for your next adventure. Turn a normal sheet into a sleeping bag insert by sewing it into a sleave. Measure the inside of the bag and cut the sheet to fit. Sew up the bottom and the sides. The sheet will keep your sweat off of the sleeping bag and can be simply thrown into the wash when you return. If your tent develops a musty smell, set it up in an dry, airy place and sprinkle salt inside. The salt will absorb the moisture and smells. Leave it set up overnight and remove the salt. You can also use borax.
