Whilst this is probably an ideal book for a beginner, anyone with even a small amount of experience in either chain or mail construction will quickly outstrip this book. Projects are generally made with inexpensive materials (copper, titanium wire, rubber O rings and so on) with a few using precious metals. The selection of tools required is basic and inexpensive, which will probably please those just starting!
Disappointingly, the rings are all unsoldered; there's remarkably little on finishing techniques and there are no tips on making the work easier (e.g. stopping the work moving around too much during assembly). The gallery section that runs to a couple of pages is quite good, however.
Reluctantly, I have to concede that the available online resources are a better bet, although they are usually devoted to armour.
