If you can carve Radha Krishna Murti very nicely, it will be a great service to the society. There is a quality of wood, which is very hard and strong and black and heavy; in India we call it iron wood. I think it is called ebony here. If you can carve Krishna from this ebony wood, and Radharani from another wood, one which is very hard, and of golden color, and from this same golden wood, Lord Caitanya (all of Them 24" in height, and Radharani a little less) then you can begin this work immediately. I'm so glad to learn that you are eager to serve Krishna in every way possible. This mentality is very rare, and I guess that you must have been engaged in Krishna's service in your previous life. To begin eager to serve Krishna is the greatest achievement after many many duration of pious life.
