The odd vaguely aqua color is from a “Souffle pen” that K & I discovered on a recent excursion to the west side of town…. I’m afraid to say it was a pretty disappointing new pen. Not only did it not pouf up nearly as much as implied by the name (or perhaps it lived up to the finicky nature of souffles?), but I ran mine dry in just over a week. Hmmmmmm.
