WHAT DOES A flag mean? Obviously the answer comes from context. Burned it’s one thing, tattered another, strewn on a coffin something else entirely. The flag, the US one, at least, is inseparable from its moment in history, from this moment in history, and just after the Fourth, the question of meaning and flags seems apt. They’ve been central in installations and performances by Liz Collins, knitter, artist, textile designer. Back in 2005 she and an army of knitters made a giant knit flag on Governors Island as part of The Muster (think: art camp meets Civil War re-enactment is the best way I can describe it). Called Knitting Nation 1, it was her first knit performance.
