After I post the final arrow tomorrow - Arrow #10 - then you can send your contest entry to me at email@example.com. You must have two correct answers for each of the 10 arrows for your entry to be eligible to win, so check your entry carefully. Each panda can only send in one entry, and you must send it from the email address that your account is registered to. You can read the rest of the rules here.
Hat Day is still going strong! I will visit once more at 5pm Pandanda Time today. Here are some pictures I took during my earlier visits:
Hats off to you all!
