Building dry rock walls is one of the techniques that takes patience and a lot of skill, I’ve seen people who’ve “got it” and those who simply don’t. Assuming that something is easy to do because it is made from simple materials is a sure fire way to fail.
Respect the craftsman for what they can create with their hands, and if you want to learn, be prepared to sit at the feet of a master craftsman and understand that there is an art to working with your hands, whether as a carpenter, mason or any of the related trades.
I first wrote about working with your hands back in 2006. These jobs once held a place of honour in society, perhaps that is making a comeback?
