What can i do with old pots and pans?

You could use as planters if they have a cool vintage vibe, or paint them a fun color with spray paint.

You could make a pretty good set of wind chimes with old pots and pans. Maybe hang a couple large serving forks and spoons with them.

I use old pots, and pans as a base for Christmas trees. Wire or glue tomato cage to the pot, wire the top of the cage closed to form a cone for the top of the tree. Add a lighted garland by wiring it to the cage spiraled down the cage. Add, decco mesh, or burlap, fabric, or whatever works for your decor to spiral down the cage to fill in the rest of the space. If your pot or pan is not the right size, try flipping it over, using the pot upside down. If the pot is smaller, cut the cage down, and make a smaller size tree. I hope the picture helps explain what I wrote.

I would add some glazing to make them rusty and create containers for the garden
