At Dony's Creations you can find two patterns for two different little fish. If you have a lot a scrap yarn, these fish are a great way to use it, since you can make them any color you like. You can also use them as a key chain.
The pattern is in Italian, but don't let this discourage you from making them, on the side of the website there is a gadget which will help you to translate.
