Many, many moons ago I made a smock from moleskins, a bit like a fisherman's smock with long sleeves and round neck and as far as I can remember I used about 30 of them - by the time I trimmed 'em to a decent edge and a fairly uniform shape there ain't much area to each one............I remember it being a long and very smelly job involving much salt and allum amongst other stuff, and a hell of a lot of scraping, stretching and drying. When I had it finished and was pleased and proud of it, my then GF decided to run off to the States with my "best friend" and took it with her...........never saw any of the three again!.....atb mac
