So, after a bit of thinking and staring and sketching, I've decided to do...
Pidgey!
I like that I can make a bunch of bits I haven't made before (hat, cute bag, pleated skirt, wings) and I think I'd like to wear something slightly feminine for once ^^; I know the brown top looks like a shapeless bag, but I'm planning on making it a bit more form-fitting.
Yay for costume plan!
Now, to apply for jobs and plan my train trip :D
