I was at a blogsite http://villagecarpenter.blogspot.com/ and followed a link to some archived video. I spent the better part of a day watching and marveling over these glimpse into the past. I think it is the fact that these were utilitarian items made for everyday use and although some artistry was involved most important was that the piece function. These craftsmen developed the skills to economically produce a no frill product. If you can take the time to watch you will notice that there are no rulers, just a few measuring tools and not many other tools at all.
I forget exactly what all twelve were about,but some of my favorites are the bucket maker, the wheel maker, and the shoe maker. Some others are nail making and blacksmithing, button making, pottery and wall paper printing.
I eventually found a web page translator widget at google that translated the text of the site but actually enjoyed just watching the videos not knowing what was going to start.
