Are there others?

Aside from the Winterlude event that's in it's second year (c/o Spins & Needles), I've only ever seen one independent knit...

It went up about a year ago on Glendale and Percy, right across from a friend's house where I koozied up their front railing. The bright yellow has faded a touch, but it's survived a lot, including the current construction where they pulled it down a bit, but didn't remove it to make room for their markings.
