I got the basic idea for this lantern from this site, but I’ve substituted LED tea lights for the real ones for safety and convenience.
You can make one and decorate your desk, or make a bunch and decorate all your windows. Or make a string of them and hang them in a chain. It’s an easy project to do with kids. I did this with my son’s Cub Scout den and they had a great time customizing their own tikis.
These tikis also make great alternatives to pumpkin jack-o’-lanterns, if you can’t get pumpkins or don’t want the mess of making one.
