Yarn Bombing Los Angeles (YBLA) is a group of guerrilla knitters who have been collaborating since 2010. YBLA stages public installations and performances to help expand the definition of public art to embrace street art, including self-initiated, ephemeral urban interventions utilizing fiber material and craft techniques. Collaborative art making, community building, public outreach, blurring boundaries between contemporary art practices, graffiti and craft are integral components to YBLA's practice.
The group organically grew out of a participatory yarn bombing event organized by the Arroyo Arts Collective in Los Angeles and became an entity of its own during the six month process of putting together Yarn Bombing 18th Street, an interlacement of site specific installations featuring 65 local and international knit graffiti artists. YBLA projects range from the day long urban intervention outside MOCA's seminal Art in the Streets show to conducting knit graffiti workshops for LAUSD teachers, students and their parents.
YBLA's current project CAFAM Granny Squared that brings together an internatonal community of 275 artists and crafters to cover the façade of the Craft and Folk Art Museum with granny squares in May 2013 is the collective's largest and most expensive endeavor to date.
