My favorite Tree of Life mythos is that of Yggdrasil of the Norse, but can be found across almost every culture in time. 

This shawl pin is fired in a raku kiln, is about 1.3" in diameter, is wrapped with silver colored wire, and finished with a miniature bamboo knitting needle. The wire is semi malleable so that you can adjust the pin as necessary to fit your piece.

Each piece is individually glazed and fired so there will be variants from pin to pin.
