Since I'm up early... and I love coffee... I thought this mug was the perfect pick today! This is from Etsy seller chiarashandpainted. You have to click on the link to see the rest of the pictures - her adorable handpainted design includes a little worm on the other side and a handle that reads "early bird". Too cute!
BTW - if this doesn't suit you, there is also a Night Owl mug!
