I'm happy to help with your napkin Christmas tree! Here are some instructions to get you started:
1. Gather your supplies: You'll need a napkin, a pair of scissors, and some string.
2. Fold the napkin in half, then in half again.
3. Cut a triangle shape out of the top layer of the napkin, leaving the bottom layer intact.
4. Fold the top layer of the napkin down, and use the string to tie it around the base of the tree.
5. You can now add decorations to the tree, such as small ornaments or ribbons.
