The thread about horses made mention of using animal fibers for goods and that made me think - how many people know how to spin, weave, knit, sew? I'm fortunate that I'm one who sews and knits. I have a loom that I used years ago which I could resurrect is needed. I don't spin but I think I could pick it up pretty quickly if I had a a wheel. Wheels and looms would command a premium price in a TEOTWAWKI situation. For that matter, having spinning, weaving, sewing ability would certainly be a valuable skill to barter. We all have our BOBs and in-home storages but how about gaining skills on the more traditional home art skills that might be needed.
