<3 it! I'm definitely considering diy-ing our baby items this time around. Fluffy creatures is not quite our style. I've always liked the Adams-esque nursery theme from the movies. :) Looks great!
You know, I totally considered a knife mobile, too. Not for long, mind, and DH wanted no part of it, but I certainly did. Instead, we decorated his room with bones, creepy art done by friends & bits of metal from a scrapyard. Well out of reach, naturally.
Here's a shot of a monster made of random bones found on hikes by our friend in CA.
