1. Start with 6 toothpicks and form a square by placing them so that they form the four sides.
2. Take the remaining 6 toothpicks and divide them into 2 equal groups of 3 toothpicks.
3. Join each of the 6 loose ends of the initial square with 2 of the extra 3 toothpicks, forming 6 new sides.
4. Each side should now consist of 2 toothpicks, creating a larger square.
5. Repeat steps 1-3 with the new square, using the remaining toothpicks, to create 4 smaller squares.
6. You will end up with 6 identical squares, each made of 4 toothpicks.
Remember to be precise in your placement and ensure that all sides of the squares are even and symmetrical.
