2. Rectangular folding: There are two methods for rectangular folding; One is a double rectangle, which is the same as the first folding method of square folding; The second is a multi-layer narrow rectangle, which can meet the requirements of different shapes by changing the number and distance of folding layers.
3. Strip folding: Strip folding is a method of folding napkins directly after flattening them, or folding them in half first, so that towels become multi-layer thin strips. The method of strip folding is as follows: double-sided overlapping method of parallel folding and diagonal folding on opposite sides.
4. Triangle folding method: Fold the opposite corners of the napkin into a two-layer triangle, or diagonally fold the bottom of the triangle into a four-layer triangle. On the basis of triangle, the folding shape is changed by folding, turning and inserting.
5. sawtooth folding: fold the napkin in half according to the rectangular folding method, but don't overlap the two corners. The four corners should be staggered to form two serrations respectively, and then the corners should be folded in half to form a double tooth shape.
6. Sharp corner folding: one corner of the napkin is fixed, and both sides of the corner are folded to the middle or rolled into a sharp corner. This method is suitable for folding an object with a big head and a small head.
7. Extraction and folding: straighten the napkin, block the center of the napkin or the midpoint of the four corners or sides with your fingers and lift it directly, or fix the center, rotate the edge around the towel, and then extract and fold it. This method is relatively simple, but it should be noted that the four corners should not be tilted when extracting, and the folded towel corners should be the same size, otherwise it will affect the beauty of the shape.
8. Folding, folding and folding: One corner or several corners of the napkin are formed by folding, or folded first and then folded, and a folding method combining turning, folding and folding is adopted. The folding of the corner combination is troublesome, and several corners are folded at the same time. When assembling, you must be very careful not to go wrong. Otherwise, it can't be molded.
9. Diamond folding method: Fold the two sides of the napkin twice against the center line of the corner to form a ginger folding method. By changing the times of folding, the distance between the remaining two ends of folding can be adjusted, or the width and width of the middle overlapping part can be changed, so as to achieve the purpose of different shapes. For example, many birds and some animals use this folding method.
10. Right-angle folding: a method of folding the edge of a napkin into a rectangle and then folding the corner of the towel upward. Towel folding angles include single folding angle, double folding angle and cross folding angle. By changing the level of folding, the number and size of turning angles, we can achieve the purpose of transforming different shapes.
