Obvious question: just what is that?
Fun is the primary goal of thing-a-day; that said, it also creates a prime opportunity to improve our space in a more practical way. This bargain-basement contraption is none other than our new laundry drying rack. We originally envisioned a freestanding rack with legs (from an ironing board, say) but quickly realized that we could just as easily set this frame across our bathtub.
Which brings me to an important point about thing-a-day (and life in general): simplify where possible. Judging by the semi-official thing-a-day site, this annual creative sprint is not meant to become a second full-time job; half an hour per day is all it takes to build something simple, cool, and possibly functional. (Also remember the famous dictum: form follows function.)
