In planning Miss Cozy's Marie Antoinette Hello Kitty birthday party, I have loved using Zazzle, which allows customers to create custom postage, labels and more, and is the most fun. EVER.
It's against the rules to create custom items from licensed characters (like Hello Kitty), but why worry when they have these items on offer ... who wouldn't love to receive an invitation with the stamp above...
And this patisserie stripe return address label?
And these stamps for Miss Cozy's thank you notes!
