Last year I chose a Minion hat because it was too cute to pass up. I found the pattern here on Ravelry. I didn't have the right yarn and I think I went off the pattern a bit too so it ended up a tad bit small for J's head (but it still stayed on). I added a yellow shirt and overalls and ta-da!!
This year I'm going to knit him and his brother dinosaur hats. How much free time I have will decide how elaborate the rest of the costume will be. Since I'll have L in a carrier I want to create an egg that is cracked open to put over the carrier. I'd love to make something like this tail for J too! If I still had time after that I'd make a hat for myself and my husband (if he'd agree to wear it).
Anyone else make their own Halloween/Harvest Carnival outfits?
