Instructions

Take the green pipe cleaner and feed it through two holes of each button, starting with the largest buttons until you have the tree-shape desired. 

Twist the bottom of the pipe stem to form the base of the Christmas tree. 

Form a loop with the remainder of the pipe stem and twist together.

Take the silver pipe cleaner and fashion into the shape of a star. 

Twist the remainder of the silver pipe stem around the green pipe stem to attach the star to the top of the ornament.
