I know several people that have used these doors as closet shelves!! I think they had to put little spacers in after they cut them to fit their closet, but they work great for them!!

A friend of mine in college used one as a desk, propped up by some wooden crates. Kind of rustic looking, and the crates were great for storage.

I also use one as a surface for a desk. I have two, two door filing cabinets either side propping it up. It’s a perfect height.

artists use the wooden outer layers (called ‘doorskin’ oddly enough) to paint on, so if you are artistic, or know someone who is just pry that shizz off! because it can be really expensive in art stores.

they make good shelves. I have a snake and a large lizard tank supported on one of these bad boys. Can also work for desks (lay one across two filing cabinets).

We needed to bolt a piece of plywood to our block wall in lieu of a gate. To strengthen the plywood, my husband cut the hollow core door damaged by our dog in half and screwed it to the back side of the sheet. It’s very sturdy now.

We also used it as a table for our last yard sale by setting it on top of two empty cat litter pails (see your April 2 post!)

If the wood was somehow made water-proof, the inner bit could be used for planting small, long-rooting plants. Probably not going to be used much, but still!
