Plumless focuses on three gauges of wire - 18, 16, or 14 - for the 25 projects in the book, and uses a math formula based on Pi to determine the size of the jump rings needed for each design. The majority of the designs are derived from a Byzantine chain pattern, and the author actually explains that the books is "dedicated to unraveling the mysteries" of this particular pattern. While I felt this was mainly a chain maille book, he has provides instructions for incorporating beads into some of the designs, some using more wire to connect the beads to the links in the maille and some using beading wire to weave the beads into the chain patterns.
To help you finish off our chain maille designs with hand-crafted findings - which only seems like the right thing to do since you crafted the entire chain by hand - he includes instructions for how to make findings such as ear hooks and clasps. And, of course, there's a lot of information on forming jump rings and how to determine jump ring quality.
Those who have already attempted chain maille will find lots of ideas and patterns to try out. Jewelry makers who have never created chains will find beginning-level information to help them get started, though I hesitate to suggest this as a guide for someone who has absolutely no wire jewelry experience at all. My one tiny issue is that I prefer smaller jewelry, so I would have liked to see use of 20-gauge wire as well, but that is obviously a matter of personal preference because this book (128 pages including color photos) is really packed full of information.
