I had decided to make a neck pouch from the Amadou I recently harvested, and I thought, well, why not make it a challenge and make it with stuff procured in the woods. I still had that hare rib, so I decided to make a needle from it. Sourced ethically, by the way, taken with permission.
I drilled the hole first with the awl of my trusty Victorinox Outrider. Take care not to apply too much pressure, the material cracks easily.
Carving the sides, really carefully, I actually reverted to a fine sandstone. Make sure to get rid of all the marrow and to remove all the dents and nicks.
Et voilà....bone needle.
Not sure about the twine, though. I am not good at that sort of stuff, so I will maybe just take twine I have. But we will see how it all turns out. Maybe some nettles...we will see.
