For this ornament, you will need a variety of pipe cleaners- definately one green for the base of the tree. First, fold a pipe cleaner into a triangle, take the edges and fold them over and shape out the tree.
Next, take a red (or another color) pipe cleaner, form it into a rectangle and wrap the edges around the bottom of the triangle.
Take more of that color and wrap- measure a little over the length and cut the pieces for a smoother wrap.
Take another color of the pipe cleaner and measure a bit longer than the top of the tree (leave a tiny hole) and start wrapping. Go 2-3 layers, then switch colors and keep going until you reach the bottom.
Smooth out the tree and reshape, if needed.
Take a white pipe cleaner (or another color) and cut about 3-4 inches. Stick one end through the hole and wrap the ends together to use to hang the tree.
