The pleated Christmas hearts is a Christmas tree decoration staple in Denmark and Norway. They’re allegedly going back to Hans Christian Andersen, and are fairly easy to make. Since the look of it changes depending on which kind of paper you use and the look of it.
Traditionally, red and white is used, but using wrapping paper or carton gives it a different look, and you can easily match it to any decoration scheme you’d like.

If you haven’t pleated these before, it might be easier to start with fewer strips on the hearts, but once you get the technique down, add more strips.
It’s also possible to pleat patterns, but then you have to cut the parts even more carefully to ensure they fit together.
