We also strongly recommend 당신 send in pictures of girls (heck, even boys) in headbands, especially our Gossip Girl cast. We've got a bunch of graphics here, but 당신 can also make your own (we'll make an entry where 당신 can share them).
The mailing address is:
The CW Network
c/o Gossip Girl
3300 West 올리브 Avenue
Burbank, CA 91505
Now aside from old school letter sending we'll be doing 이메일 and other forms of communication/promotion. So get ready for that too. If 당신 can't send in printed headband photos, then 당신 can certainly do it online.
Don't forget to keep promoting The Headband Project!
