1. The simplest three-dimensional greeting card is a grid-drawn three-dimensional greeting card. Here we take a heart-shaped three-dimensional greeting card as an example. Since this is my first time making it, I used printed grid paper to make it. There are also some pre-painted three-dimensional greeting cards online. Just download them, print them out and cut them yourself according to the markings.

2. Fold the paper along a grid line. Generally, the image part of the three-dimensional greeting card is unevenly distributed. That is to say, there are either more images above the line or part of the image below. many.

3. Outline a heart shape on the grid, and since there are 3 squares left above the heart shape, there must be 3 more squares below the heart shape to make the whole thing embossed.

4. Use a knife to cut out all the vertical lines. Just keep the top part of the horizontal part, and keep the horizontal part of each square in the lower part.

5. Make sure that the knife cuts all the parts to be cut, and the paper is not pulled together.

6. Then fold the paper so that the entire heart shape bulges out, so that it has a three-dimensional feel.

(In fact, the expressiveness is still two-dimensional)
