I've come to think of these as Niwot Mugs. They just feel to me like the little town where I live and have my pottery, and I don't make any other piece that looks quite like they do. I made one of these a few months back, and I keep using it and carrying it around. Now you can, too.
Niwot Cafe Mug
10 oz. 3 1/2" tall. Microwave & dishwasher. Each of these is made one at a time and carries its own distinctive character and subtle variations in the decoration, but you'd have to look closely to tell them apart.
