Created by renowned metalsmith Bill Fretz in response to consistent demand from working jewelers, these blanks are cut from seamless extruded tubing and arrive prepped and ready for forming, hammering, and finishing.\u003c\/p\u003e\u003cp\u003eEach blank measures \u003cstrong\u003e2-1\/4\" diameter x 1-1\/2\" wide\u003c\/strong\u003e and is ideal for larger wrist sizes. Made from a malleable brass alloy of 70% copper and 30% zinc, the tubing is cut to length, edge-finished on a belt sander, annealed for workability, and given a basic tumbled finish—saving you significant prep time in the studio.\u003c\/p\u003e\u003cp\u003eThese blanks are featured in Bill Fretz's instructional DVD, where he demonstrates forming and hammering techniques to create finished cuff bracelets. The 2-1\/4\" diameter is especially well-suited for larger wrists. Available in multiple diameter and width combinations, this family of tube forms offers flexibility for a wide range of bracelet styles and wrist sizes.\u003c\/p\u003e\u003cem\u003eNote: When creating convex (domed) forms, doming will reduce the finished diameter of the piece.
