And now for something completely different.

Next textbook looks to be right up my ally.

Sewing Machines.

Sewing machine history. Early machines. Machine types and purposes. Attatchment types and purposes. Sewing machine ergonomics and the human body. Upper threading. Lower threading. Timing. Tension. Cleaning. Lubrication. Removing burrs. Causes and prevention of breakdown and failures. Repair.

This shouldn't be to hard.

But I'd like to know why sewing machine history is so important... I'm not downing it, just trying to figure out why somebody who wants to be a tailor would need to know detailed history of the sewing machine.

Witty dinner conversation?
