LINCOLN, Neb. (AP) — Lincoln officials have pared down a proposal for putting knitted artwork in Union Plaza in celebration of World Wide Knit in Public Day.

A local group of knitters proposed “yarn bombing” the park to celebrate the day in mid-June.

Yarn bombing is done in defiance of city rules. But this this group wanted to receive permission before it placed a stocking cap on the sculpture of a large head. The knitters also had plans to colorfully cover tree trunks.

Not much of the proposal was left after city officials scrutinized the group’s plans, ruling that yarn bombing cannot embellish any outdoor sculpture and may only be applied to nonliving objects.

Parks and Recreation Director Lynn Johnson says he’s willing to discuss the matter.
