①把圆对折。②再平分三分然后折。

在图(4)上可以剪出六瓣的雪花。
拓宽思路和想象,如:
在上图④的基础上整体对折如图(5),再从边上沿箭头向里剪,这一剪可以大可小全凭你的喜好,就把雪花的瓣分出来了。图(7)是图(6)的展开图。分瓣是由图(8)剪形完成的。有时简单的剪几下,可以出现漂亮的图形。每个剪纸者都兴奋不已。
注意:图(8)造形是剪的关键所在,怎样剪呢?可剪成圆如秋月,或剪形尖如麦芒、方如砖块、剪缺如锯齿、剪线如胡须、剪口要整齐。不能剪过头或剪坏别处。

引伸:如,五角形的剪法,正五瓣梅花的剪法
1、五角形

(1) screen.width-500)this.style.width=screen.width-500;" border="0"> (2)
screen.width-500)this.style.width=screen.width-500;" border="0">(3)
screen.width-500)this.style.width=screen.width-500;" border="0">(4)
在(2)图上随意剪,会出现意想不到的漂亮的图形。
2、梅花
