how to make a paper christmas tree easy

It's easy to make a paper Christmas tree. Here's a quick step-by-step guide: 1. Cut a square of paper into a triangle by folding one corner over to the opposite corner, and cut off the excess. 2. Fold the triangle in half lengthwise. 3. Unfold the triangle and cut a small slit in the center of the fold. 4. Fold the triangle back together, so the cut-out edges are on the inside. 5. Fold the triangle up along the slit to make a 3D tree shape. 6. Decorate as desired with paper cutouts, stickers, or glitter.
