Cute! I love rusty things in garden. My fav piece of yard art is a bowling ball I covered with pennies ( old so they tarnish) after a few months it looked just right. I used silicone 11 glue and it is still holding. You could use old washers too, I would think. I put it up on a piece of pipe using one of the holes to hold it up. Sorta like a gazing ball. Can't find my picture. Lost ball during hurricane Katrina.
