I know how to sew do you?
I have sewn before, but not much. Just general repair or making pouches. Do you use a sewing machine or just a needle?
I use just a needle, but in the stone ages people would sew fur and skin using bone, pretty crazy huh
They had to poke the holes first with other flint tools, right? The prep of the fur and leather is more interesting to me. 
Yeah, I think it's pretty cool that it's been done by hand for thousands of years.
