I used drywall stilts. They're easy to learn to walk on and terribly comfortable to stand on for long periods of time, unlike traditional stilts. In truth, I spent a lot of my time leaning against a wall or stairwell. Only until I absolutely had to move did I walk around or put a lot of weight on them. Sorry I took so long to respond, I just noticed this feature.
Hi! I just saw your scarecrow picture from last year. That is what I am going to be this year. That costume of yours in cool. How ever did you manage to stay up?
