Vintage Spoon jewelry Topic rhendric September 24, 2012 at 7:10 pm #47549 Having a heck of a time flattening silver plate spoons to make jewelry. Using rubber mallet on concrete. They all end up with ripples. Any easier way to do this? It is frustrating! Discussion Anonymous September 25, 2012 at 12:23 pm #84216 i use rubber also, but its the concrete that is giving you the bumps…you need a smooth steel surface… Anonymous September 24, 2012 at 11:33 pm #84199 The article I just read says to flatten them on an anvil using a heavy mallet (not a rubber one). Hope it works! You must be logged in to reply to this topic.
