So something thing like this, I guess.
I'm not making a single picture for the left and right parts. It can work for simple designs, but every time the mask came out a little different. And everybody use a different shape.
So I'm just putting the important parts where they can't be cut out (like... chick should be a little up, just to be safe).
@pollomostro oh gosh! I would totally wear a dress using this as a fabric pattern, it's so cute <3
