Glue 2 googly eyes about 1/3 of the way down on the clothespin.
Glue a red pom pom just under the googly eyes to make the reindeer's nose.
Bend pipe cleaner in half, then bend each side back and forth to give the antlers a zig-zag shape. Glue onto the back of the clothespin.
Add ribbon or twine for hanging, if desired. You could simply clip the clothespin ornament onto your tree instead. Be sure to allow the ornament to dry fully before hanging on your tree.
