Use measuring tape to determine the center point of the birdhouse roof, then mark it with a pencil. Add a hole-saw attachment to a drill to make a hole in the top of the roof.
Once the primer has dried, apply color to the birdhouse.
For a whimsical touch, consider painting the roof and the base of the house different shades of the same color.
Thread the cord of the pendant kit through up inside of the birdhouse and through the hole in the roof. Screw filament bulb up into the socket of the pendant kit. Once secure, plug pendant kit into outlet.
