Material preparation: several pieces of cardboard; A pair of scissors; A bottle of glue and a gel pen.

1. Fold the cardboard in half and draw two hearts with neutral strokes, as shown in the figure.

2. Cut out the heart shape with scissors, and cut out strips from one side of the straight line to the inner side of the heart shape, which cannot exceed the curve of the heart shape drawn from the inner side, as shown in the figure.

3. Unfold the cardboard and lift the strips alternately.

4. After being folded in half again, apply glue to the unobtrusive part and stick it on one side of another folded cardboard.

Matters needing attention in making three-dimensional greeting cards:

1. The overall tone is consistent with the theme.

In the process of making stereoscopic cards, the most important thing is to match the overall tone of stereoscopic cards with the theme style. For example, when making three-dimensional cards with a strong festive atmosphere like Christmas, the colors of Christmas are naturally red, white and green. When choosing patterns, Santa Claus and Christmas tree are also the first choice.

2. The material style matches the theme.

Selection of materials is also very important. When making three-dimensional cards, we should pay attention to the selection of raw material styles that match the theme. Relatively textured paper can give people a relatively simple and advanced feeling, while relatively bright and smooth paper gives people a relatively advanced feeling. In this regard, the production of three-dimensional cards needs attention from design to material selection.

3. Pay attention to the collocation of small patterns.

When making three-dimensional cards, it is also very important to pay attention to some meaningful small patterns, such as hearts and stars, which have the feeling of showing one's mind and strong lovers, and also have certain meanings. Skull is suitable for boys to tease each other. The use of these small patterns can match the details with the overall tone.
