Just the kinda book i needed, as it shows so many different ways to approach wall building. Something for everybody and for every type of stone. The most useful information I found were the illustrations of what not to do, and why, with certain shaped stones.....this has saved me a LOT of trouble, as I'm learning from scratch. The book is beautifully laid out, with very clear illustrations. Another plus is - that it has a flexible and well protected cover and is bound in such a way that means you can have it with you on-site, without it getting ruined. The whole thing is really well thought out, which is unusual, thank you and well done to who ever put it all together.
