I got the hats in the mail today...thanks!!
Here is their fun journey: I knew you'd mailed them monday, so by yesterday I thought the post office was just being slow. whatever. anyway, today i came home to a random envelope in front of my apartment door. I looked more closely, and it was the hats! My best guess is that a neighbor accidently got it in their box (it was addressed correctly btw) and for some reason OPENED a piece of mail addressed to another person and addressed to another place. Who does that? At least they made it safely to my doorstep. I'll try them on the chickadees later and post pics!
You are the best!
