I once made a Shaker Peg Coat Rack sort of thing for a player -- a piece of 1x4 with Shaker pegs from a Hobby shop spaced about 6" apart.  The one I made was about 24" long, and held 4 dulcimers.  It attached to the wall with sheet rock anchors.

Molly, I just use a regular picture hanger and string or wire.  See this picture of a wall in my office/music room.  In that case I used leather shoe laces to hang the dulcimers from the hangers, but for a more discreet look you could use fishing line, which is really strong but also nearly invisible.

Can any of you offer suggestions or recommendations for hanging dulcimers on a wall? I’ve seen dulcimer hooks online that are quite simple, but priced at $12 and up! I would appreciate your suggestions and ideas.
