Next, cover the carton with (pretty) duct tape for added durability (and awesomeness). Cut the take out container to separate the top from the bottom. Place the milk carton so it is sandwiched between the two layers of the container, and hold in place with duct tape. Wrap duct tape around any exposed adhesive on the sides, as shown below.
Hang your lovely birdfeeder outdoors and fill the bottom tray with your favorite bird seed. Enjoy!
