The strings actually make a sound when strummed even tho they are not metallic. I have put gold metallic strings on a musican's cross with a guitar on it which was a little smaller, but they were just for show. Will post a pic if I can find it tomorrow.
The wood is Marblewood, but I think I used a piece of scrap Aripari for the thingy on the side of the sound hole. Really has a beautiful grain to it. Givin some serious thought to trying to make a tiny pick for it and either a guitar case or a stand for it. LOL
this is the one I put the metallic thread for the strings. Guitar was way smaller tho. Box is only 3 x 5 or so.
