joshuatree.....You just have to do it.....you can find out some stuff through books and the internet, but doing it is the best way....try a barbecue in your yard, a pier, anything. You can pick up a few pointers from different guys. Your eyes are your best friend, as scale and balance are huge. If you have pride, you should do ok.....In my mind there is nothing, NOTHING more hideous than bad stonework.....and that is usually done by guys that a) don't know, and b) don't care......it sounds like you care, so with time and patience, you should be ok....ps....get some nice stone....if you're not blessed with patience, tough stones will drive you to drink
