How to make envelopes

The method of making envelopes is as follows:

1. Fold the paper in half according to the middle edge. Don't bend it obliquely. When folding, press the scratch with your finger. Then, fold it to the center crease line inside and press it to both sides, that is, this square paper currently has three creases.

2. Fold in half to the central crease line. Don't turn over the last crease, fold the edge in half to the central crease line.

3. Seal the upper corner of the letter. Fold the thick part in half at a 45-degree angle, and do this at both angles.

4. Fold inward. The 45-degree angle folded in the previous step is folded inward along the other side of the isosceles right triangle.

5. Find the center point. At this point, more than half of the success has been achieved. Find the center point of the edge that is not folded in half.

6. Fold a right angle. Fold one side and two corners of the center line just found towards the center line respectively.

Letter cover format

1. Write the recipient's address on the first line of the envelope. The handwriting should be neat and the place names should be detailed. Place names should be written from provinces, cities and counties to districts, streets and house numbers. If you are writing to the countryside, you should also write down the names of towns and villages. There are six squares in the upper left corner of the envelope, and the postal code of the recipient should be filled in.

Write the recipient's name in the middle of the second line of the envelope. According to the identity of the recipient, you can write "Cong Comrade" or "Cong Mr. (Ms.)" after the name. Do not write titles here, such as "Cong Grandpa".

Write the address and name of the sender on the third line of the envelope. The sender's postal code should be filled in the lower right corner of the envelope. In the case of difficult delivery, the post office can quickly return the letter to the sender according to this information.
