This Lemontree Creations DIY cupcake costume is so cute, and you don't have to sew anything! That's right up my alley.
I thought about making her a gingerbread girl using a brown fleece-y suit, but this cookie sheet idea is pretty funny.
There are several DIY tutorials online for this costume.
Of course, I'm still weighing some non-edible options, too. What are you guys (or your kids/pets) dressing up as for Halloween?
