Like what? Want to make them or use them?
most columns would not be "free" standing on their own. Depends on their size what you could do with them. Frame a wide doorway, use on a porch, We have a pair at the end of our driveway, which I love (free from a neighbor) these came with lattice! You could use t hem for fencing. Post a pic of them and you will get a lot more responses.
You could wrap with seasonal declarations.
