Thanks Joe. I really appreciate that.
Dave, Cav pointed you in the right direction. Karl's Dragon hide blanks really caught my eye. Then I (almost literally) stumbled onto a couple of unopened Pine cones that looked like they might be able to hold up to being drilled and turned without being stabilized, so I decided to try them out. I just kept soaking the blanks in thin CA as I was turning them and they held together pretty well.
The Pine nuts that were still in the unopened cone are what makes the interesting patterns - the ones that pull out from cutting the blanks or while being turned I filled with thick CA and are dark colored, the ones that manage to remain in place are the light colored ones.
Not what I was expecting at all, but pretty unique.
