Chalk Mural Lettering - Froth

We have to fill the massive chalkboard that is our entrance wall with something non-christmassy, so we've set the whole studio a challenge: come up with a word to do with the business and illustrate it in any way, to then be drawn in chalk. The responses were weird, wonderful, sometimes downright unrelated, but now comes the fun part - illustrating them. First off the bat, Dwight, with FROTH.
