Thanks for posting this! Very pretty bow, and the scalloped edge is cool. I'm doing some academic research with Ojibwe communities in Minnesota, so it's cool to see the traditional style (and material) showing up here! One quick question: I'm new to backing wood with wood - what's the virtue of backing a piece of wood with the same type of wood (i.e., Birch with Birch)? Why not just make a thicker self-bow from Birch rather than laminating another piece of the same wood on the back? I'm sure there's a reason to do that, I just don't know what it is.
