I still remember when one of my professors, in a lecture about culture-changing innovations, discussed the eyed needle as both a major technological innovation and a proxy for much more. Eyed needles imply sewing and it is not a major leap to conjecture some level of tailored clothing and bags. Leather was abundant in hunter-gatherer societies and can be made into many things. Humans moved into cold climates early on and well-made clothing is a real boon in that environment. Unfortunately, for the archaeologist, such small, degradable materials rarely survive outside caves and rock shelters. The best, oldest example I am aware of in the Americas is the Horn Rock Shelter in Bosque County, Texas. Have a look at the short history below and check out the Texas Beyond History page for more about Horn Shelter.
