To make a large paper Christmas tree, you will need some construction paper or card stock, scissors, glue or tape, and decorations such as glitter, sequins, or ribbon. First, cut out a triangular shape from the paper to form the basic shape of a tree. Then, cut out smaller triangles of various sizes to create the branches of the tree. Once you have cut out all the branches, arrange them on the tree in a way that looks natural and pleasing. Finally, glue or tape the branches to the main triangle and decorate with your chosen decorations.
