我的爷爷爱好剪纸的英语作文

My grandpa likes cutting paper. He can make paper change into different shapes. Some of them are like animals. Some are like clouds. Also, some are words meaning good fortunate.
They are very interesting.
However, cutting paper is difficult for me. Because there are many rules and skills. For instance, different colors must be suitable for differnt designs. You must know "hongshuangxi" , used for weedings. What's more, you must be good at drawing and using tools.
It is my grandpa's hobby. He keeps it for 20 years.
