The projects were designed by a variety of jewelry designers, and I am guessing most projects were reprinted from a collection of previously published books. This is just something to keep in mind. I see a pretty good amount of jewelry books on a regular basis, and I can’t say that I recognized any of the designs.
One other possible issue is that some project use very specific materials that not everyone may be able to acquire that easily. For example, there is a really cute bracelet that includes souvenir penny charms. I did a brief search online to see if I could quickly find vendors that sell these and had no luck. I would guess with more time and effort you may be able to find somewhere to purchase these, but they are not supplies you could find at most craft stores for example.
For beginning jewelry makers who like charms and want an economical book to help you with basic techniques for using them as well as design ideas, this book is definitely worth considering.
