第一步是“折”。
The first step is to fold.

把一张正方形的纸沿着对角线折成三角形，然后再对折一次。

现在就可以开始“剪”了。
Now we can start to cut.

窗花可以不用很规则的设计。

首先剪出一个弧形，作为花瓣的轮廓。

之后用剪刀随意剪出各种曲线或锯齿。
After that use a pair of scissors to cut different kinds of curved lines and saw tooth.

也可以剪出半个“心型”。

最后一步是展开，这个时候要轻一点，免得撕破较细的连接处。
The last step is to open up with light touch to avoid tear the fine connections.

然后轻轻展平，你会发现，所有随意的形状都变成了美丽的对称图案。
Lightly flat it, you will find a beautiful symmetrical pattern from a random cut.
