Form an equilateral triangle using three of the toothpicks.
Use the other three toothpicks to form four smaller triangles inside the larger triangle by laying them across the first three such that each of the added toothpicks bisects two of the original toothpicks. The second set of toothpicks will extend beyond the first set, but they will form four equilateral triangles inside the original one.
