Those weird and creepy crown/mask things were one of the most memorable parts of Lady Gaga's "Bad Romance" video. But they're actually pretty simple, and you can make them yourself with stuff you probably already have at home. This video shows you how. (Of course, if you're planning to wear this to a party or something, bear in mind that you won't be able to see anything!)
Paper, approximately 3 feet by 2 feet
Adhesive velcro strips
1. Cut a line of tall spikes into one end of the paper.
2. Cut a triangle out of the other side. This is where your nose and mouth will show.
3. Put some velcro on the far left edge of the paper, on what will be the the outside of the mask, and on the far right edge of the paper, on what will be the inside of the mask. These strips will join together to keep the mask on your head.
4. Now you're done, so get your Gaga on!
