Making a paper Christmas tree is a simple and fun craft that can be done with just a few supplies. First, you'll need to gather some materials: a piece of green paper, scissors, glue, and some decorations like stickers or glitter. Cut out a triangle from the green paper, then fold it in half lengthwise and cut along the fold to create a diamond shape. Unfold the paper and fold the two short sides up to the middle, creating a three-dimensional tree shape. Finally, decorate the tree with stickers or glitter, and display it proudly in your home!
