I have recently came across Beaducation which is a terrific resource for metal stamped jewelry making supplies and online classes. Many of the classes are free! I have purchased several classes and found them all to be very good and reasonably priced. The line of stamps from Beaducation are also premium quality. Metal stamping is very popular these days and Beaducation at www.beaducation.com is an excellent resource. Other companies that sell quality stamping supplies are PJ Tool and Supply at www.pjtool.com and The Urban Beader at www.theurbanbeader.com.
