Have you met Jay Mohler? Saying he makes God's eyes is like saying Michelangelo painted ceilings. They are incredible, intricate works of art.
Jay sells finished yarn mandalas (as he calls them) on his etsy shop. They range in size from about 18 to 24 inches, though you can also special-order a huge four-footer. He also sells kits with everything you need, or just the special notched sticks, or just the secrets of the universe (i.e. directions for making your own ojo de dios mandala). Seems like a great craft to get into with an older child!
