I have a set of copper pots. What can I do with them
You can use them for decorative pieces or planters.
If they are old, copper pots can be retinned so that they are usable again. There are a couple of companies in the US that do it.
use as planters, to store towels, or other items
Hang them on your wall.
Sell them, gift them. Sought after by fine cooks. Or just decorate with them, some great ideas above.
Planters are always the first think that comes to mind.
I would fill them with small stones and soil. They would make beautiful planters!
