Goosey you just get pine fence poles and paint them :)
I have some lovely jump wings that we bought for a bargain price (5 pairs with poles for $500 and they are solid pine, there is probably $2500 worth of wood in them), they will last for years and years and they're great to have. I plan on making some standards one of these days so that I can move my jumps around a little easier, the ones I have are more "set and forget" so although they are great they're not very flexible. With standards I can get some plywood and cut out designs to make some more "scary" jumps. I want to do butterflies, fairies, a horse design like CM's, and I'll probably make a wall eventually. Oh and a pair of elephants or giraffes!
Edit; two of my poles are BIG branches cut to length but they are very much set and forget because they weigh a ton. I have a pair of natural pine jump wings that make a very nice "natural" jump.
