3D paper stars like these were such a hit when I was a kid. My youngest sister used to make lots of these and fill up a glass jar in her room. They are fun and easy to do, too - very kid-friendly as long as you provide the strips. The steps can be found here.
Aside from just making these stars as decoration, you can put little notes before folding them. Maybe put some words of encouragement like what Creative Kismet did, or maybe some wishes so you don't have to wait for a shooting star in the sky, or probably things that you are thankful for.
