Look on Ebay for somebody selling anti-tarnish cloth by the yard. A single yard will be enough. Take it to a dry cleaning store that hems skirts and pants (assuming you don't know anybody with a sewing machine). Have the cloth sewn into a simple bag with a drawstring. Or you can get fancy and have the bag tailored, which adds to the cost and does nothing for the anti-tarnish protection. I got fancy with mine and made them sax shaped with zippers, but anything that fits inside the case will do.Anyone have a source for a bag big enough for this task or any other recos?
This is what I did for my silver-plated Keilwerth ToneKing alto. I bought two yards of the cloth on amazon and sewed it into a bag (really more like a pillowcase).I bought 1 yard of Hagerty anti-tarnish cloth from Amazon after having my silver-plated soprano overhauled in the spring.A lady down the street sewed it for me into a bag. Very simple, and she was happy to help me.
