Ed,
You have some great ideas. I love these. I assume their bottle stopper blanks.
Thanks for posting these pictures as well as all of the videos. I learn something each time I watch them, even if I can't yet duplicate them.
One of the guys at our shop is a fly tier (tyer?). I wonder if I could do one of the itty bitty flies in a PR blank for a pen. Being a Baptist he hasn't the use for a bottle stopper, lol.
