In addition to the two authors, the other designers are Jenny Dowde, Jennifer Hansen, Yoko Hatta, Karen Klemp, Carol Meldrum, and Luise Roberts which means a very wide-ranging group both geographically and for types of projects. The 40 projects range from easy to complicated. The instructions at the beginning of the book are really thorough (47 pages) and cover some unusual techniques not usually found in a crochet book such as hairpin crochet and cable techniques. Lots of intro material also on working with beads and pages on the materials used with lots of color illustrations. The techniques are illustrated in color and can be applied also to regular crochet items. Not every project uses beads. The variety of threads or yarns is huge and only the generic term is given for them. Wires are listed by gauge; e.g. 28, 32, etc. I didn't find any crocheted ropes in this book or instructions for them. Items are necklaces, bracelets, earrings, pins and rings. I was confused by what kind of nylon threads are used as just the generic label isn't very explanatory. Lots of unusual and attractive projects each with skill level indicated. No duplication between this and the other crochet jewelry books I've bought. Glad I bought this one.
