Origami manual bagging course

The course of origami handmade bag is as follows:

1. The materials to be prepared are a piece of A4 paper, a pair of scissors, a pen and a ruler. Put the paper on the table, making sure that the long side of the paper is above and the short side is below. Draw a square outline on the paper with a pen, and then cut the paper along the outline with scissors.

2. Align the upper left corner with the lower right corner of the paper, and then align the upper right corner with the lower left corner. This folds the paper pair into an isosceles triangle. Fold the bottom edge of the isosceles triangle upward so that it coincides with the top edge. In this way, the isosceles triangle is folded into a right triangle.

3. Fold the two acute angles of the right triangle inward so that they coincide with the corresponding obtuse angles. This will fold the right triangle into a square. Fold the left and right sides of the square inward so that their bottoms and tops coincide. This will fold the square into a smaller square.

4. Fold the four corners to the center point so that they coincide with the center point. Then fold the corners of both sides down so that they coincide with the bottom. Finally, the top is folded down to close the opening of the bag.

Precautions for keeping origami by hand include avoiding touch, humidity and direct sunlight, using transparent boxes or frames, and avoiding folding and bending.

1, avoid contact: origami works are easily affected by fingerprints and stains, so it is best to wash your hands and keep your hands clean before touching origami works.

2. Avoid humidity and direct sunlight: Both humidity and sunlight will cause damage to origami works, which may lead to fading or paper deformation. Therefore, origami works should be stored in a dry and ventilated place to avoid direct sunlight.

3. Use a transparent box or frame: Putting the origami works in a transparent box or frame can effectively prevent dust and moisture from entering and protect the works from being damaged.

4. Avoid folding and bending: origami works are usually made of thin paper, so unnecessary folding and bending should be avoided to prevent paper from tearing or deformation.
