You do need some translucent origami paper to create this window star. Here is the kind I purchased from Amazon: ORIGAMI PAPER
In the video below, you can watch me create the “spines” of the star out of each color of paper and then glue them together into the final star shape. You also get a sheet of brown and a sheet of white paper in this pack. You can use those to practice making the spines if you’d like, or you can use them for a different origami project of your choice.
