Reconstruction of the Egtved Girl's Clothing

String making, says Hardy, was an essential tool of the paleolithic person. String was used in prehistory to tie things up; to make clothing (as in the string skirt of the Iron Age Egtved girl seen in the glamorous drawing); to make bags for carrying things; bowstrings for hunting; nets for fishing and small game trapping; to hang decorative pendants. And, in an extraordinary case, to make quipu, that communication strategy of 5,000 years of South American society.
The problem is, as Olga Soffer and James Adovasio have pointed out, that vegetal matter is only very rarely preserved in archaeological contexts. Oh, sure, we can see it when it is used as decoration for clay pots, and sometimes it will burn and be preserved in wattle and daub houses, but by and large, when it rots, it's gone.
On occasion we're very lucky indeed. The earliest sites with direct evidence for string making include Ohalo II in Israel (ca. 19,000 years bp), Lascaux Cave in France (ca. 17,000 years bp), and Fukui Cave in Japan (ca. 15,000 bp). Chances are good, though that string making has been around a lot longer--perforated beads have been found at Howiesons Poort/Still Bay sites like Blombos cave in South Africa at some 75,000-80,000 years ago.
