So I saw a costume of Yoda in a store and was totally "I can do that" (when, no I really couldn't). Despite that, this is the first outfit I've sewn myself, so I'm proud of it.
The robe is just broadcloth that I sewed as a robe, then added a hood and made a brown belt. The ears are just a wrap around headband and layers of material sewn together to flop over the little guy's ears. The light saber is store bought.
Unfortunately, my model doesn't stand still. So here are some action shots. The ones where he does not have the light saber, well, he's working up a temper tantrum. He really likes his light saber.
