Damn, those dulcimers are gorgeous. Luthier is definitely on my dream list of hobbies that I know I'll never have time for but would love to get into.
My problem is that I've always had more hobbies than time, and I keep seeming to accumulate new ones. The ones that I've stuck with are guitar/bass, fishing, hunting, gardening and brewing. I'm always looking for new experiences, so I find myself picking up new hobbies through friends. Some stick more than others.
