This is a Vietnamese site, but it is about KIRIGAMI, a Japanese craft, that has become very popular in Vietnam in the past few years (Actually, Kirigami probably was first developed in China which has its own style of paper cutting craft).
In kirigami papers are cut and assembled to create silhouettes of objects and scenes.
If you do not want to make your own kirigami, there are sites where you can order hand cut or laser cut Vietnamese kirigami cards and pop ups.
There are lots of patterns to chose from here:

You just need a pattern, some long fiber paper and a very sharp knife or iris scissors to get started making a kirigami.
