Please, please, PLEASE don’t “Yarn Bomb” tree trunks or any living plant with acrylic yarn. It looks cool and it’s cheap but the synthetic fibers encourage disease, mold, and insect predation. Also, any acrylic yarn “harvested” by birds for nest building poses the same hazards for them.
Some of that"'art" give you a headache, and it is scary depressing. The problem is that anybody who can hold a can of spray paint is a self-proclaimed artist, when in reality they are annoying, destructive vandals. We are living in the Ward in which a lack of talent is called creativity. If we like it or not, we are forced to look at the work of somebody's oversized ego. VOID, life without ugly and depressing street art is better.
