For Halloween, our little Lukester was Yoda. And let me tell you, it was the easiest costume to prepare! The hat took a couple of days, but if I was to just sit and do it, it probably would have only taken me a few hours.
I did the base of the hat using this pattern. But you could probably use any hat pattern. To make it not itchy and warmer, I sewed in fleece lining, that way he can wear it all winter. As for the ears, well...let just say I winged it and I'm not sure how I did it. The I simply used a towel for the robe part and just sewed it with arms and tied a tie around it. So as I said super easy.
He also happen to be 9 months around Halloween so we had to take some 9 month pics with this cute little pumpkin.
