Ya know for a second, I thought I was acctually going to see a picture of a cowl you made FOR a penis, not OF a penis. I was looking for a picture of a penis with a cowl on it...idiot!
Haha, actually, I've made one of those before. Meet my first yarn project EVER, the penis warmer for my boyfriend. (Yes, it's a little small, but I got bored really quickly of knitting, haha):
I made it pink and added a bow and his intentials for humor's sake. :p
