Christmas card practice is as follows:

First of all, bring us ready cardboard. Ordinary cardboard can be, because this cardboard to become the final Christmas card cover, so it is better to be a little more sturdy. Fold the long side of the cardboard in half, as shown in the picture. The main body of a simple Christmas card is now complete.

Next, the green paper with the aid of a ruler to draw the lines shown in the figure, pay attention to the width of the lines. The first is 3.5 centimeters, the second is 5 centimeters, the third is 6 centimeters, and the fourth is 6.5 centimeters. In fact, there is no strict definition, you can completely according to their own preferences to determine the width of this, but don't let him end up inside the Christmas card looks a little weird on the line, basically there is a gradient on the change can be, after all, the Christmas tree is the protagonist of the whole card.

After the front is drawn. We fold the paper along the long side, which is similar to the field edge folding that was done earlier when we made the Christmas card shell, and we do the same now. Once the folding is complete, we have the folded pattern shown in the image.

On the basis of the previous folding step, make another fold in the same direction, and when the folding is complete, press the origami model flat, and this time we get a small folded rectangle structure as shown in the picture. When the above step is completed, we need to fold the origami model again in the same direction. After this folding the paper has become very thick, but this is not the end, because we need to fold the paper one more time.

As described in the previous step, the folded model needs to be folded in half again. Here the folding is sufficiently completed. As you can see, the folding is such that it is easy to think that you are making an origami fan, and it is hard to think that you are making a Christmas card.
