One of the things I'm noticing as a result of yarnbombing is a heightened sense of my place in this community. The tree above is outside the hospital where my two nieces were born, and putting those two rocks in the tree feels like a small anchor to that place. There is a small pink tag around the stop sign at the corner of 17th and Wilemar, which I pass everyday, and it acts as a small marker to me on my way to and from work. It's one of the points of contact where two strands of the web of my life meet. It's a bit like mapping the world, leaving landmarks that I recognize as having a distinct connection with my life, even if it is a small connection. Try it. You might like it.
