The Wordsmith's Forge

I think the yarn guide will come in very handy. Since the book only tells you how to create the texture you want (zig zags, stars, lace, etc.) and doesn't actually give a pattern for a work, it doesn't give a weight for the yarn to use. Though I might need to check the front of the book. It has tips for the basic stitches there and may explain which yarn to use.
