In a dark little café pub near the Black Forest in Germany, I came to love hot drinks served in ceramic white pint glasses. Reliving those gemütliche college days every time I sip tea, Earl Grey, hot is easy with IKEA’s lovely and affordable POKAL tumblers.

Slurping the first sip of a hot drink is one of life’s little pleasures, but hard to do without a mug handle. After perfecting a custom cozy, I wanted to make one for my sweetheart for Valentine’s Day that wouldn’t embarrass him at work. A touch of geekery and voilà: I love you in Morse code.
