John: I've used 5 gal buckets for garden stools many times. My husband had a shed full of 5 gal empty buckets from sea salt he would buy for his aquarium. At one time I even thought it would be a neat idea to paint a few of them and make some round cushy pillow tops ... and have a couple here and there around the garden. I kinda thought they could be made to resemble garden mushrooms.
Hetty: I like that little garden scoot of yours too ... I really like the idea of having a stationary bucket type stool as John described but having one with wheels would sure come in handy too ... and a drink holder for my iced tea ... Yeah!!!
