This pattern is simply titled Crochet Necklace, and is offered for free by a Ravelry user called creativeyarn. Here are the end results of my foray into the world of crochet. The model is Yaawireds herself, who got to take the finished item home after the photoshoot. The rest of the yarn will be used to make a lovely shawl for her.
PS: My photographer was not available, so I had to make do with an old digital camera. The difference in quality is so clear, isn't it?
