My favorite crochet resource. I learned to crochet with the Crochet Crowd and I recommend this site for anyone, beginner to advanced. A plethora of free tutorials (both left and right handed) as well as many free patterns and other resources.
The Crochet Crowd has put together a tutorial for how to crochet your very own temperature afghan. Click here to access their tutorial or see the video below.
