Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.

Who ponders the sock? This common object is something people tug on and take off daily with hardly a thought. Unraveling the garment's history, construction, and use, Kim Adrian's Sock reintroduces us to our own bodies—vulnerable, bipedal, and flawed.

Sock reminds us that extraordinary secrets live in mundane material realities, and shows how this floppy, often smelly, sometimes holey piece of clothing, whether machine-made or hand-knit, can also serve as an anatomy lesson, a physics primer, a love letter, a weapon, a fetish, and a fashion statement.

Object Lessons is published in partnership with an essay series in The Atlantic.
