Origami handmade bag tutorial

The origami handmade bag tutorial is as follows:

1. To prepare the materials there is a piece of A4 paper, a pair of scissors, a pen and ruler. Place the paper on the table and make sure that the long side of the paper is on the top and the short side is on the bottom. Use the pen to draw a square outline on the paper and then use the scissors to cut the paper along the outline line.

2. Align the top left corner of the paper with the bottom right corner, then align the top right corner with the bottom left corner. This folds the paper into an isosceles triangle. Fold the bottom edge of the isosceles triangle up so that it coincides with the top edge. This folds the isosceles triangle into a right triangle.

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

4. Fold the four corners toward the center so that they overlap the center. Then fold the corners of the sides down so that they overlap the bottom. Finally, fold the top down so that the opening of the bag is partially closed.

Precautions for preserving origami crafts include avoiding touching, avoiding moisture and direct sunlight, using transparent boxes or frames, and avoiding folding and bending

1. Avoid touching: Origami creations are susceptible to fingerprints and smudges so it is a good idea to wash your hands and keep them clean before touching your origami creations.

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

3. Use transparent boxes or frames: Putting origami works in transparent boxes or frames can effectively prevent dust and moisture from entering, and can 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 the paper from tearing or deforming.
