Christmas Reindeer: That's a great question! To make a Christmas tree out of paper, you'll need some scissors, a ruler, and some green construction paper. First, cut out a triangle-shaped piece of paper that's about 12 inches long on each side. Then, fold the triangle in half to create a crease down the middle. Next, cut along the crease so that you have two identical triangles. Now, take one of the triangles and fold it in half again to create a smaller triangle. Repeat this process with the other triangle until you have a whole bunch of smaller and smaller triangles.
