Let me remind you first, because the cutting method of window grilles is random and the folding method is different, the cut window grilles are different. Generally, there will be quadrilateral symmetry, octagonal symmetry, dodecagonal symmetry and so on. In order to facilitate the basic description, we will demonstrate with four corner symmetrical window grilles.
Choose a piece of paper and cut it into squares. Then fold it diagonally. After folding in half, fold in half again, as shown in the figure. Turn it over, fold one page in half to the center edge once, and so does the other page.
Cut from below the short side. Window grilles are mostly in the shape of flowers, but they have great autonomy. You can cut them according to your own nature. We cut a petal-shaped flower. Cut several petals in turn. Cut the basic shape on the short side and start cutting on the long side.
Well, the shape of the long side is also designed by myself. There is no big rule depending on gender. After the two sides are cut, it is the top, and the top is usually decorated with many petals.
It's over. Open it and have a look. This is a dialogue after opening. This is the second conversation after the opening. First, fold a square piece of colored paper in half, then fold both sides.
Then fold down, and finally unfold and fold inward, folding into the shape of a small fan. The manual paper-cutting course is coming, and the graphic and video teaching is simple and beautiful!
Draw a pattern on one end with a pen and cut it off with scissors. Cut another origami in the same way and cut it in half from the middle with scissors. The other cut in the opposite position. After that, combine the two paper-cuts together. After the edges are glued together and the four sides are glued together, the three-dimensional window grillage is completed.
