Well, the first step is to gather the supplies you'll need. You'll need some construction paper or card stock, scissors, tape, and some decorations like ribbons or glitter. Once you have all the supplies, you can begin by cutting out a long strip of paper, about 12 inches long and 1 inch wide. Then, fold it in half lengthwise. Next, cut out two triangles from the top of the strip to create a tree shape. Glue or tape the triangles together to create the shape of a tree.
