Think creatively based on what materials you can get easily/cheaply. I had a bunch of tires that were retired (pun intended) from keeping visquilene over rows of round bales, so I have tire structures. I drive past a well drilling company every day on the way to work, where they throw away used black plastic water pipe every Tuesday night, so I have black plastic water pipe structures. I got some used concrete sewer tiles, 2' to 6' in diameter, free from my FIL and our excavator; in they went.
