There are many ways to fill crystals with energy, but first, they need some cleaning. Easiest way is flowing warer for some minutes, it can be tap water but spring water is the best.
Some days ago, @zitus told me a way to charge them with cosmic energy and gave me two rhinestones.
Here is the method:
Step 1: I put the stone in a stick like this. There is a natural hollow on the wooden stick, and the crystal exactly suits in it:
Or this way: I drilled a hole in another stick, and placed the crystal:
Of course, i sticked them with a 2-component glue, to avoid the crystals falling.
Step 2:
I pitched the sticks in the ground (connection with Mother Earth), and let them there for at least one week. They will get the power of the Sun, Moon, the stars, Mother Earth and some rain (i hope):
These sticks will be rattle handles, the two-pronged will be a double rattle. Next time, i would like to show you how to make rattles from leather (i have also learnt it from @zitus and her partner, János.)
