My favorite teacups are two that I got, one that's white with the word "tea" impressed on either side in the ceramic, and the other is red with the same "tea" impression. They're made by the Beehouse company, I think you can find them online. I just think they're cute. When I go home, though, I've got a new black-on-black cherry blossom print mug from Target that I'm fond of. Though if I'm making a pot of tea with my mom, I get out my grandmother's Blue Willow teapot and cups. But I'm a Blue Willow fan, so go figure.
Mmm teacups.
