A claw-hammer style, banjo playing friend of mine showed me how he makes his fingerpicks out af a plastic milkjug handle. he broke his fingernail off on his strumming finger. He cut the handle off a gallon milkjug, and trimmed it until he had a little piece that would cover the end of his finger. Then he trimmed it to fit.
    I tried this, but I soaked it in real hot water, before the last trim, and then slipped it on my finger to trim it. It cools to give a custom fit to the finger. Yeehawww!!!!
