Let's see----what about using chairs? Take 2 chairs and use a board or heavy piece of cardboard for the middle section. Ladderback chairs can also hold a curtain rod, or metal rod, for hanging clothing.
Also, if you have a couple of trees that are close, you could use a clothesline thingy and hang clothes on it. I've seen sheets used, too. Sometimes I get a bit lazy, though, and hate to bend down. Yes, I'm lazy.lol
Oops! Another thing you might could use is trashcans, turn them upside down, and again, use board, or heavy cardboard to do a makeshift table. Good luck with it!
