Great White Shark amigurumi by Sir Purl Gre. Free crochet shark pattern. This is a simple pattern that will show you how to subtly shape a piece by placing increases and decreases right next to each other. You can use whatever colour of yarn you wish for the main body. Search up different species of sharks. They come in so many different colours so you might be able to find a use for that variegated yarn that you bought because it was interesting but you have no idea what to do with it!
