This is a Christmas ornament. (duh...) The inspiration for this was from my "tirforce earrings" and I had the thought to make an ornament. The hole is 8mm. I used some basic robin and some wire that was lying around the house to hang it on the tree.

This string will work for this ornament:

These wire hooks will work for the string to hang the ornament:
