Classical Loop-in-Loop Chains by Jean Stark
This is the book that taught me how to make these gorgeous chains. Unlike chainmail, a torch is required for this chain technique, since you fuse or solder the (very thin) rings into unbroken circles before weaving them together. The illustrations are clear and easy to follow. The chain weaves are stunning. Highly recommended.
