Made from large size baby shampoo bottle. I don't have step by step instructions (sorry!) but I did use a knife to make initial cuts (careful!) and then used scissors to go back and round out edges so no one gets poked. I made the "bottom" that fits over the faucet just big enough to fit through (so it will stay on) and even kept some of the plastic around the top of the hole so it would help it point downward. I will try to make another one soon and post step by step. Sorry!!
