"You should wear wool"

Which actually makes me think of a rather cute scarf idea - make one of those fake-fox boas, only change the shape and the yarn, and do a sheep.

except you'd either need to do loop stitch (I HATE loop stitch) or find a nice fluffly white or natural wool boucle for the wool part. (It HAS to be wool. I can't imagine doing a sheep-scarf out of not-wool, unless of course you're allergic.)

I suspect a little playing around with the Vegan Fox pattern would work. Make the body fatter, change the shape of the head, make the body longer and the tail a short little nubbin, do the feet and face in a smooth black yarn. (Interesting thought, that - converting a fox into a sheep. Like beating swords into ploughshares?)
