Here is a polishing tip from @lucywalkerjewellery - “A really handy technique for polishing those hard to reach areas, called thrumming 👍🏻😍” I asked Lucy what type of string she is using here and she told me thick embroidery thread, but you can also use cotton cord, or kite string! The polishing compound here is ZAM. Which the cord secured by a vise or hooking it onto something you can pull it taut and move your piece around or you can secure your piece and move the thread around. Who uses this technique?!? Tell us how you do it below! #PolishingJewelry #Thrumming #ZamPolishing #jeweler #metalsmithsocietythrowback
