A toothpick, I can do that. I have already changed the strings back to the size that came with the dulcimer, I had gone from a 14 to an 11 so I could tune higher. I am back to DAdd & the 14 for an A, for a performance . The next time I want to go up to key of F or G (The tuning I did for 'This is My Father's World' - with chopstick as a hammer and a wine stopper as a noter ;-) will give all these ideas a try. I have several slots and only when I changed to one of the extra slots did the string ring.
Below is the ring, prepare for horrible:
Thanks so much,
