Being a jeweller by trade I am always on the look out for excellent jewellery techniques books and have recently found one. "The Workbench Guide to Jewelry Techniques" by Anastasia Young. It will be delivered to my workshop soon. I can't wait!
It's a comprehensive guide to jewelery making techniques with step by step photos and is a great reference book for learning new jewellery skills - there is always something new to learn in this business.
