still folded, cut a small upwards slit toward the eyes but not through them. that forms the beak. while it's still folded, push the beak out from the body a little so you can draw a little outline down the edge on both sides.

to get your owl to hold onto the invites, first fold the little zig-zags out to the front. roll the invites up fairly tight, (between a pencil and marker sized), and slip it though the little holes at the bottom. try to flair the talons over the top as much as you can, but it is just paper so be careful. i ripped a couple.
