Step 1

Remove the red flag and the door handle. Then, drill a 1-1/2" hole near the top of the door.

Step 2

Drill a 5/16" hole below the larger hole. Using a handsaw, cut a round dowel to 3" long. Paint the dowel in a color of your choice (we used Valspar spray paint in Real Red). Let dry.

Step 3

Paint the mailbox (we used white Rust-Oleum spray paint). Let dry.

Step 4

Carefully drill a 1/8" pilot hole in one end of the dowel. Then, from the inside of the mailbox door, insert a 5/8" panhead screw through the small hole you drilled in Step 2. Attach the dowel to the screw.

Step 5

Re-attach the flag and mount the birdhouse on a post or hang from a tree.
