For months, Mandy Greer has been crocheting with strangers. She has taken her project to crochet events at coffee shops, galleries, museums—basically, to whoever would have her—and now all of those people are part of her 200-foot-long "fiber river," which will be installed in an urban forest in West Seattle for the rest of July, open to visitors and thinkers and photographers. This week, for one night only, dancer and choreographer Zoe Scofield will perform with the river, blurring the lines between figure and ground as much as she possibly can.
