WEST CAPE MAY, N.J. (AP) — Someone is spinning quite a yarn over one New Jersey shore town.

An unknown person dubbed The Midnight Knitter by West Cape May residents is covering tree branches and lamp poles with little sweaters under cover of darkness.

Mayor Pam Kaithern says police are looking into the guerrilla needlework, which technically is against the law because it is being done on public property without permission.

The mayor and many residents admit they’re enthralled by the rainbow of colors that has popped up.

Resident Susan Longacre takes a walk each morning in Wilbraham Park, where several tree branches and light poles have gotten the treatment. She thinks it’s great.

Even those who aren’t thrilled admit the yarn is better than spray-painted graffiti.
