Extreme crochet is not for the faint hearted. Imagine the biggest hooks, the chunkiest yarns and some stuff that's not even yarn at all and you're on the right track. Extreme crochet is fun and addictive, quirky and thought-provoking. And immensely satisfying.
Choose chunky, high-loft woollen yarns, or fabric and T-shirt yarns, string, rope, washing line or even make your own. If it's long and cord-like, then you can probably crochet with it...
