Who this book is for
- You know how to sew — you just don't know what the machine is doing when it goes wrong
- You’ve lost an afternoon to rethreading, or waited two weeks for a five-minute repair
- You want to look the problem up like a bird book — not read a manual cover to cover
- You own a machine worth protecting and want to fix it without fear of making it worse
