Yesterday, I found some craft books about Monkiri.
It was japanese paper cutting technique.
I tried one of them. I found the patterns and how-to guide here(Sorry, Japanese only).
I folded a paper in two, and then in five.
According to the pattern, I cut the paper with scissors.
I made a flower. It's simple and beautiful. It was very easy. But many other patterns are difficult to cut, only with scissors.
Then, I tried to apply it to sewing.
I cut a cotton cloth with this method and made a pouch.
It's a little bit difficult to fold and cut the fabric like paper. So I put a thin interlining to sharpen it.
