Upcycled Truck Brake Drums

For the last 2 days we have worked tirelessly in our yard.  Pulling weeds, planing flowers, planting our garden, clearing out clutter and so on.  Speaking of clutter we had these huge truck brake drums sitting outside the yard.  They used to keep the boys' basketball hoop from tipping over.  That basketball hoop is now gone and new one in it's place so there was no need for the brake drums.   I didn't want to get rid of them.  I thought they would make neat planters.   I grabbed a can of spray paint and painted all 3 of them white.  Then I added the potting soil and the flowers.  I was trying to go for a stacked look with 2 of the brake drums/planters.  It wasn't doing what I wanted so it is tilted.  I love how it turned out.  Please share with me what you have upcycled.
