FARGO, N.D. (NBC) -- Fargo, North Dakota is working to protect its unique street art from vandals.
Knitters recently stitched up designs on Fargo street lights, known as "yarn bombs", but vandals quickly tore most down.
"We had 43 sleeves that were put up Friday," says lead yarn-bomber Mara Morken. "By Saturday we had less, and by Sunday we had 25 remaining. 18 sleeves were destroyed or stolen."
News spread about the vandalism and City Commissioner Mike Williams decided to step in to help.
Williams took the rest of the sleeves and moved them up the poles, high, out of harms way.
Morken and the rest of the artists are working on knitting and sewing more creations so Fargo can be yarn-bombed once again.
The knitters say each sleeve can take 40 hours to make.
