I have found the tarnishing of metal components to be a somewhat distressing problem. I want to start making some pieces to sell but worry that the items will tarnish after the buyer has had it for a while. I'd be interested to hear what others are doing to deal with this problem.
There are several posts dealing with your problem (mine, too). Just put 'tarnish' in the above Search box and check out the results.

I just inform the customer that the item is made using sterling silver and that it will tarnish. To help keep the piece looking it's best, I suggest you keep your price in a plastic zip-look with a piece of white teachers chalk. This will help retard the tarnish process.
