Went to a comedy club Sat night in the East Village, and we passed by this. Of course I had to snap some shots. I think this is probably an Olek yarn bomb, but I don't know for sure. The pics I saw of her grocery carts are different designs/colors.
You probably know it drives me nuts when people confuse knitting with crochet (like confusing Phil Collins with Genesis), but I guess I get it. Still, I am so surprised by how many legitimate articles about Olek's work call it knitting. If I were an artist and crochet was my primary medium (which is basically true except I don't make a living off it), I would get "sick of tired" (Workaholics??) that pretty quickly.
