Neat sheets are great! Think of a blue tarp that is fabric on one side and water resistant on the other side. They are great for picnics or beaches (or lining the inside of car when taking landscaping home! ). when you unroll it you can put the cloth side up and its nice to sit on, but the tarp-like bottom side keeps it dry from dew on grass, or sand, etc... They are also technically washable so they are reusable although they are fairly cheap to replace.
