That's cool Brian. :)
I have a Cretan Lyra as well, that I play like a tiny cello on my lap. Wish I had more time to get better at it!
Look up Google images of lyre bows, psaltery bows, and rebec bows. It can be as simple as a bent stick with horsehair in the notches.
If you are interested in gourd fiddles, you might take a look at the West African varieties of one-string fiddles, since they are played by the same cultures who play banjo ancestors. My favorite name for them is the onomatopoeic "nyanyar" but "riti" is also used. Lots of other names too. Their bows are the simple sort Strumelia just described--a bent stick with horsehair in the notches. Here's a YouTube video of a guy playing the riti.
I had a gut feeling they'd be shipped today.
Boo. Not fair.
John, what type of varnish do you use?
