You won! I'll send out the shirts next week.
TO RECEIVE YOUR SHIRT:
Please fill out my fabulous new CONTACT FORM with your mailing address. Include your screen name and your shirt size (S, M, L, XL) in the comments section. And someday your photo will appear here! (Yeah, so far it's just me in the shirt. But that's about to change!)
FairyHedgeHog: Thanks for the link. Please email me your mailing address, too! Do you personally know Old Kitty? If so, please include her size, as well (mailing 2 shirts to the UK isn't much more expensive than mailing one). I hope that the picture will include Charlie the cat.
I'll have another shirt giveaway next month. Tell your friends, unless you're worried about that awkward get-together in which you both show up wearing the same shirt.
