Hematite and Seafoam
The two colors used in this tree, go together well. I need to find beads of a similar color. I know they have Hematite beads. Hematite is very common and used to make iron actually, and grows in kind of a crystal like form. This tree is two colors of wire wrapped around a silver frame with a white shell moon.
Study how water flows in a valley stream, smoothly and freely between the rocks. Also learn from holy books and wise people. Everything (even mountains, rivers, plants and trees), should be your teacher.
