* Build in a place that has wet, well-packed sand. Sand that is too dry won't hold together.
* Build close enough to the water to make mixing easy, but not so close that the waves will attack before you're done.
* Clear your building site of seaweed, stones, and rubbish before you begin. Be sure to clean up again after you're finished. Recommended Reading:
