what i do is find a group of trees...usually 3 that make a triangler shape...then i cut some palm fronds or sweet gum branches and put them around the trees.
i also make a roof out of the branches and palm fronds but that's a lil time consuming but well worth the effort....i usually stock up on the lil chairs that come in a bag from WalMart...about 5 dollars give or take a dollar....the palm frond hides any movement from the waist down and then i have the trees and roof to help cover movement from the upper body.

good luck...hope you find something that works for you.
