1. First of all, the opening of the carton, that is, the side with the plastic mold, should face itself. Then, use scissors to cut the middle and lower part of the carton along the vertical left side of the plastic mold, and then cut it along the edge of the carton, so that there will be a small door. If you think the plastic mold is not good, you can tear it off. There is generally a diamond on the side of the carton, which can be removed to make a vent and a small window.

2. Find a carton with similar length and width, then fold it in half, roll up the long edge with a pen to make it slightly tilted, and stick it on the carton with transparent glue from the inside, which is a bit like it.

Add some fences and puppies around the small house to make the house look more beautiful.

4. Disassemble the cardboard box, cut out the needed cardboard from it, and paste it into the box in the shape of a house as shown in the left figure below. Pay attention to cut off the triangular arched roof on both sides. Hand-made saving boxes have been initially produced.

5. Make the roof and chimney with the remaining cardboard, and stick the roof and the house together with adhesive tape. Wrap the inner wall of the cardboard house with white paper. Open a rectangular slot on the roof to put coins. The next step is to decorate the appearance of the small house with wrapping paper. After pasting the wrapping paper, you can write your motto on it with a marker, or draw some personality patterns.
