These little beauty's are made out of recycled water bottles. Basically you peal off the label and then color them in with sharpie markers. Once they are colored you snip off the bottom and then cut around the bottle in a spiral tell you get to the neck. Then tie a string around the top to hang them. Easy Peasy Lemon Squeeze. Our tree in the back yard is now decorated with them. I'm not sure how long the color will last hanging in the direct sun. But for now they look cool and It was a great rainy day project.
