This is a truly amazing book. It isn't a pattern book, it's more a showcase for creative possibilities with yarn. The pictures are gorgeous and show knitted landscapes and sculptures many of which combine knitting, crochet, felting and other fibre crafts to create one-off pieces of art.
When first published around two decades ago I think this book was really ahead of its time. I would recommend it to anyone who is interested in the ways that knitting (and related crafts) can be used as a creative outlet rather than simply for making garments.
