Purchase an old door from a thrift shop or Habitat for Humanity ReStore
For legs, I used old cedar bars from an old deck. You could also use new wood too.
Sand the legs
Drill a small hole in each corner, and insert a double sided screw.
Drill a small hole in the center of the leg, and twist it in the screw
Add basic white wood glue where the two points reach. Wipe off excess.
I then added extra wooden details for support using a drill and screws.
Great for indoors or out!
