The base for a twisty Christmas tree can be made of thick cardboard or wood. First, design a base of the right size according to the size of the Christmas tree, and then use a saw or knife to cut the cardboard or wood into a circular or polygonal shape.

Next, you can choose to cover the base with colored paper or brightly colored paper to add to the festive atmosphere. You can add decorative borders or decorate the edges of the base with ribbons to make the base more beautiful.

Finally, fix the support part of the Christmas tree to the base to ensure that the Christmas tree can stand firmly on the base.
