I just bumped into a 3-minute YouTube video of the tongue-twister song “Sister Suzie’s sewing shirts for soldiers” by Billy Murray. The video contains an original 1915 film clip from the first world war showing wounded soldiers using sewing machines, as well as video of ladies sewing for the War effort.

Did you check out the hats and pretty dresses the gals were wearing. Then it looked like the guys were working on nets of some kind and then soles on boots. Too cool, thanks for the link.
