In this tutorial, we learn how to make a paper Christmas tree. Start out with a square piece of paper, then fold corner to corner and open it, then fold it on the opposite corners and open it. Now, turn it over and fold it side to side on both sides. Now, the paper will automatically fold into it's shape because of the creases you made. Now take each of the four flaps and flatten them out with your finger. After this, cut your trunk out of your tree at the bottom, then cut slits on the side of the tree. Now, fold down the corners on the slits to make small points. When finished, you will have a cute Christmas tree in no time!
