Dry stone walling basic principles

I'm often told about a dry stone wall getting built or, what do I think of it? My usual answer is, spend a weekend on one of my dry stone walling courses and then come back to me and tell me what you think of it. While there are many good examples of dry stone walls about the place, I find it a shame in some instances where clients have paid good money for very substandard work and are unaware of the poor workmanship. The principles for dry stone walling are universal.  But hey, don't take my word for it! I have included some information below freely available on the web from The Dry Stone Walling Association of Great Britain and also the Stone Trust from the USA. I hope this information helps if you intend getting a wall built or repaired. Armed with some knowledge you will be better informed and critical when looking at examples of your potential contractor's previous work.
