(Portland, WA)  --  One of the mask sculptures at Providence Park is apparently a Timbers fan.  Someone gave the face a giant knitted Timbers hat and red beard Sunday night, writing hashtag "Beard Bomb" in sidewalk chalk below it.  The trend is starting to become known as yarn bombing.  A woman named Lyndsea Moore took credit for it on Instagram, saying the hat took her more than two weeks to knit.
