I like to think that a project isn't real until I bleed on it. Maybe I'm just clumsy. Pretty much every one of my bows has some blood under the finish somewhere.
On the fingernail thing - my friend got a thorn under a fingernail so deep it was unreachable. It had somehow gone all the way to the cuticle but the end of the thorn was over 1/4 inch deeper than the tip of the fingernail. Rather than go to the hospital, he got some sandpaper, a razor, tweezers, and a whole mess of disinfectant. He sanded the nail thin (from the top) and cut a channel to reach inside and remove the thorn. It worked. I can't imagine the pain. This was when we were teenagers, so he couldn't even get good and drunk first. Looking back, I kind of think we should have gone to the hospital - just for the pain relief.
