I decided to try a lighter set of strings and it was a learning experience. My first attempt is always without directions, kind of like playing music by ear. The strings broke. Then I watched Mandy Tyners’ video and the key is using wire snips to adjust the length first, but don't make them too short. Sigh.
All things are in place now and the dulcimer sings beautifully once again. The strings were packaged nicely and arrived on schedule.
