...anything made by Happy Clay! You can see her work on Etsy or on her website which includes a blog (and you MUST click on the Flickr link to see even more of her amazing work). I wish she would blog a little more (hint hint, if you are reading this) because I can't get enough of her work and process. If I could I would hang her cups on my wall - her glazing is THAT exquisite!
P.S. - I just bought myself this cup and I am already imagining how incredibly cool I am going to look drinking out of it. :)
