Superhero

My boy is always running around the house in a cape. He takes anything he can find - sheets, sister's blankets, etc - ties it around his neck and instantly transforms into...someone other than who he really is. I have no problem with this except when I find sheets laying around with knots in them. So I was totally excited today to find THIS tutorial. I'd love to make a whole handful of these for my two little(r) ones.
