You may print and use this triangle grid paper to help you with this drawing.

      Step One.

      Start with a large equilateral triangle.

      Step Two.

      Make a Star.

      1. Divide one side of the triangle into three equal parts and remove the middle section.

      2. Replace it with two lines the same length as the section you removed.

      3. Do this to all three sides of the triangle.

      Do it again and again.

      Do it infinitely many times and you have a fractal.

Want to take a long, careful look at what it looks like?

See a few of the steps below.

Let's see them all together
