Sewing is a vital technology, since only with sewn, multi-layer clothing was cold-intolerant Homo sapiens able to colonize the middle and upper latitudes of the Eurasian continent during the last Ice Age. In the referenced article, it mentions needles from about 35,000 years ago. Presumably the earliest garments were furs stitched with sinew threads, but plant fiber thread from 34,000 has been found in Georgia. The archaeological problem is that bone needles and organic fibers do not endure to the present like stone and copper.
