The first step in making a Christmas tree out of paper is to gather your supplies. You will need a sheet of paper, scissors, glue, and some decorative elements such as beads, sequins, or glitter. To start, fold the paper in half lengthwise and cut along the fold. This will create two identical pieces. Next, fold each piece in half again, creating a small triangle shape. Use the scissors to cut along the bottom of the triangle, creating a triangular shape. Unfold the paper and you should now have a basic Christmas tree shape.
