What you need
Before
Gather the fiber folks: knitters, crocheters, and total beginners, because the first famous tag was somebody's abandoned baby blanket. Unfinished projects are the movement's founding material. Set a monthly knit night at a cafe or library where the making happens and the plotting happens with it.
Scout small, unloved targets first: the door handle, the stop-sign pole, the bike rack, the bare bollard nobody has ever once admired. Measure with a tape and knit flat panels to size. Avoid statues and other existing art pieces; the craft is in brightening the ignored.
Set the knit nights up in Plurality and use the Needs tab for donated yarn, needles for loaners, and zip ties. Print your flyer and invite widely.
During
Install in broad daylight. A crew stitching a cozy onto a pole at ten on a Saturday morning is not vandalism, it's a conversation magnet, and the conversations with passersby are half the point. Bring the kids; they're the best lookouts who never have to look out for anything.
Seam the panels on with yarn or zip ties, snug enough to survive weather. Then stand back and watch the corner change. Sayeg's sociological test never fails: the pole nobody saw yesterday collects photographs today.
Take tag names over a bottle of wine or coffee. This is non-negotiable and costs nothing, and it turns a craft circle into a gang, which is worth more to recruitment than any flyer.
After
Photograph the knitting process and every piece the day it goes up and invite folks to record any other Moments, because the yarn fades and the photos don't. Retire pieces gracefully when they get grubby.
Then let the commissions find you. The school will want the fence done, the library will want the railing, and every workshop where the gang teaches a newcomer to knit adds a member.
