Hi Judy, quite a few of our hometalkers have shared tutorials and ideas for repurposing milk cans. You can find them all here - https://www.hometalk.com/search/posts?filter=milk%20can%227%22
I've seen them made into accent tables with a piece of wood on top and I've also seen them made into seating.
You can just go minimalist and put in an artificial plant, flowers, or ornamental grass.
I painted mine and added my house numbers to it and put it on my frount porch
