This is a reprint of The Harmony Guide to 100's More Crochet Stitches. Volumes 1-5 are all about knitting; volumes 6 & 7 are the crochet instructions. This has to be one of the most useful crochet books I have ever encountered. Volumes 6 & 7 together show you how to do basic stitches, laces, clusters, filet, shells, bobbles, loops, edgings & trimmings, some Irish crochet, various "motif" patterns, and Tunisian (Afghan) crochet stitches. The photos and diagrams are all in full color and the explanations are the best I have ever seen. Truly, they are worth every penny! If you can only get 2 books on crochet, get these.
