Here's a fun idea if you're planning a nautical themed party. Stock up on some fun decorative papers, colored pens, crayons or other ways to design a paper origami sailboat! I think every kid has learned how to fold a paper plane, but what about a paper origami sailboat? I never learned to fold an origami sailboat when I was a kid! Did you?
Watch the video below to learn how to quickly fold an origami sailboat, and then have the guests of your nautical themed party build their own. Just in case the video is not your preferred method to learn, there's also a good written description on how to build a paper origami sailboat.
Either way, origami can be a fun thing to do at a party and especially if the origami fits the theme of your party such as a nautical one.
