I did my first witchstone reading on my mother today.  They’re really not like the brand-name version, but an ancient wiccan form of lithography, or fortune telling by stones and crystals.  It went very smooth, and I hope to continue to hone this skill as with so many other interests I have going at the moment.  The following web link has information about lithography.  My version is a little different from this one, but you get the idea!
