Crystal healing

Crystal Healing has always interested me and i am on the look out for a course I could go on, most are held a distance away from where I live and I do like hands on learning. But would be interested if anyone has any knowledge and would like to share, if they could maybe start a little teaching course here in bite size, as I am a slow learner.

That would be great to have a course on here, if only a basic one.
I am in particular interested in grids. I would love to build one and such, not just lay the crystals out in a pattern.

I did in fact receive a vision for one a while back and my intent is to build an exact replica, lol, I have no idea how long that will take me!
