What were/are chain stitch machines used for?
The recent discussions of a Willcox & Gibbs and the Singer 24 got me thinking about this. I know they were used for feed sacks and the like - an easy to remove seam was an advantage there. I'm just not sure what else they were used for.
I'm thinking a Willcox & Gibbs hand crank would be a neat addition to our growing herd!
