The sand in the dry landscape sand tray is too fine

Quick answer：

Dry landscape, also known as 'karesansui' in Japanese, is a form of Japanese rock garden that uses gravel and rocks to represent mountains and water. The sand in a dry landscape sand tray should be of an appropriate size to represent ripples of water. If the sand is too fine, it may not properly represent the water elements and can lead to issues with water flow representation.
