Today’s origami design is a relatively simple one, but I love simple stuff like this! You just pleat a square back and forth diagonally across the paper, and then pinch it in the middle.
For this model, I used paper with diagonal stripes, so that the stripes approximately align with the folds. This creates an iridescent effect, as the colors subtly change depending on your viewing angle. Now, the stripes don’t align exactly with the folds, so there’s a bit of a subtle interference pattern as well. I love the idea of making these subtle interactions between the paper patterns and the origami design, but I think it rarely aesthetically succeeds. This is my favorite example.
