How to Fold a kirigami Christmas tree
In this tutorial, we learn how to fold a Christmas tree. First, start with a square paper and fold it in half, then open it and fold it corner to corner. Open the paper again, the turn it over and fold it side to side. Open it once more and fold again side to side. The paper will not automatically fall into the shaped creases and you will have four flaps. Take your finger inside and flatten all the flaps. You should have four flaps on each side and then you can cut the bottom to form a trunk of the tree. Then, cut slits on both sides of the triangle and fold down each layer where the slits are. When finished, open the paper up and you will have a Christmas tree!
