Choose one of your two hat halves, and set this aside. This is going to be the outside part of the hat!



Cut 8 six inch lengths of the black wire. You can shorten them later if you want!



Swirl one end of each of these, so you have a couple loops. Take a small crochet hook or the metal end piece of a mechanical pencil, and poke four holes about a 1/2 inch apart near the front of the hat on each side. (You might want to try the hat on to get an idea of where you want them to be. Enter hat hair, as demonstrated below.)



Push the wire through from the wrong side of the hat, so that the swirly bit is on the inside. :)



Now, take a needle and some white thread, and secure these loops to the inside of the hat so they lay flat. This will make your whiskers stay in place and be more rigid! Hooray!



Once you've secured all of them, fold them up so that you can sew the whole hat together!



This step has a ton of pictures. I got excited. Sorry. :)
