After convincing myself I really didn't need random sidewalk yarn (who knows where that sidewalk has been and isn't your stash large enough?), I walked on. But on my way back after giving my imagination time to stew about the exciting possibilities, I hunted down the loose end and started winding it around my fist. Given the possibility of satisfying my curiosity, I have a will with the strength of an over-cooked green bean from the school cafeteria.
Alas, I did not find anything attatched to the other end. When I put the yarn under the light, here is what I found.
Also, don't you think it's exciting I have figured out how to Photoshop my photos so my skin is no longer excessively yellow and jaundiced?
I got really excited last night when I thought I found another strand on the sidewalk a block away from where I found the original, but sadly it was only a stain on the sidewalk cleverly disguised as yarn.
