Cotton yarn is an inelastic fibre, which makes it slightly more of a challenge to crochet with than wool is. (That same quality makes it a great choice for specific types of projects, though, where you want the item to hold its shape!) Although some people find cotton slightly more challenging than wool, it's not all that different, and it is certainly something you can try as a beginner. If you're learning to crochet with crochet yarn during the summer when the heat makes it unpleasant to work with wool, cotton yarn is an especially great choice because it is lighter than wool.
