Cut the orange in half.
Scoop out the flesh of the orange with a spoon.
Cut four pieces of string 12 inches long.
Poke four holes around the outside of the orange. (I used a skewer)
Using two pieces of string per orange half, thread the string through one hole and out the hold opposite of the first hole to form an "X".
Tie the strings into a knot.
Hang the orange bird feeders outside and fill with birdseed.
