last-minute paper beak

Here's the easiest paper beak ever. It's feather-light, super comfortable, and doesn't interfere with breathing. The only catch is that, unlike 99% of the costume ideas out there, it relies upon a pair of glasses to wear it. Have 20/20 vision? Get a cheap pair of costume glasses; you can glue things to them, which you really shouldn't do with prescriptions (unless you're made of money). Add feathers, and go big: think Elton John. 

(Yes, that's me, in soft-pants studio-time mode.)
You only need a piece of paper, scissors, and glue for this — really! Start by folding a piece of beak-colored paper in half. Cut a triangle with the fold along what'll be the top ridgeline of the beak. Trim your folded beak piece to shape and round the corners a bit. 

This is what mine looked like when it was shaped as I wanted it. 

Next, cut a third- or half-inch-wide strip of paper that's about three inches long. Make a cut about a half inch into the center of one short end of the strip. Fold up the resulting tabs at 45-degree angles, as shown.

I'm using a blue strip of paper for the next steps to make it easier to see. You're going to glue the folded-in tabs to the inside of the fold at the wide edge of the beak. It feels a little counter-intuitive, so make sure you're not accidentally gluing it the wrong way. At left, you want to put glue on the sides of the two little tabs that are facing away from you. The photo at right is like one of those optical tricks where you don't know if the thing you're looking at is convex or concave. Here, it's concave — the middle fold is further away from you than the outer edges. 

Here's a photo showing what the beak will look like if all has gone well. If it hasn't, just tear it off and try a new strip in the same place. The glued-on tabs will be hidden inside the beak, so no worries.

Now take your beak to a mirror, and slip the tab over the nose piece of your glasses. Fold the paper around the glasses. Tape the strip to the underside of itself, if you want a slightly more permanent hold. 

Finito!
If you want your beak at more of a jaunty, upright angle, try changing the angle of the short side, as shown below. In that photo, the folds of the two beaks are at the top. The top beak has the same angle as the one I'm wearing; the bottom will point the beak a bit more skyward.
