Make shell buttons - PEM BB traditional.straw.buttons

This is a badge bit (BB) that is part of the PEM curriculum.  Completing this BB is part of getting the Straw badge in Traditional Skills.

We often take things like zippers, snaps and velcro for granted.  A common fastener in the olden days was buttons.  Let's make some!

 
 

Here's one way to do it:


Minimum requirements:
  - Make 4 buttons from shells
  - At least 2 holes per button
  - Somewhat round and smooth
  - This bb can only use materials that existed 200 years ago

Provide proof of the following as pictures or video (<2 min):
  - Shell(s) you're starting with
  - Drilling or shaping shell bits into circles
  - Drilling holes for thread
  - Finished buttons
