I recently found an origami crown in Origami for Children. It was super simple to make and I think it would be adorable done in silver or gold paper at a princess party. It's easy enough that you could even have the kids make their own.
Start with a square piece of paper folded into fourths.
Repeat the last step - flip the paper over and fold toward the center.
Repeat again - flip the paper and fold toward the center (could this be any easier?)
