In the neighborhood business district are trees with themed knit and crocheted sweaters. The sweaters are made and donated by residents and designed to reflect the nearby businesses. The sweaters stay up all year round. The Oak Park Women’s Exchange and the Art Council of Oak Park and Forest Park are the sponsors of the tree sweater project, which is formally known as Knit Knot Down the Block.
