I'm a tree hugger, and proud of it. I still like lumberjacks. and appreciate the need to feed their families, but I also love trees and owls and critters of all sorts.
My friend Leslie commented here on Otterwise a few days ago that for Earth Day this year, she created a tree cozy. (for photos, here's her BLOG ENTRY)
I really like this idea. I'm pretty sure the robin outside in the backyard wouldn't appreciate an Aran sweater knit especially for him, but I usually scatter my old wool and cotton scraps in the yard early in spring for the nest builders. (It makes for an interesting summer with bits of cobalt blue and bright pink flashing between the leaves of the maples.)
And if I were to follow Leslie's example, putting an unexpected bit of knitting on a tree I love, I'm pretty certain the neighborhood would notice. Maybe in a bad way, but I bet more in a good way.
