I've made a few st silver bails with 2mm wire, annealed, hammered and twisted over to make tube at the top. I'm beginning to wonder whether I'm better off using sheet st silver ? I know I would need a piercing saw, however, not sure what mm thickness I'd need as I've never worked with sheet before. Also not sure what size sheet to start with for a few bails and maybe a few small square pendants ? Any advice please ?
