Learning is difficult and always hit and miss. Of course it is best to learn from a competent teacher, but often you do not know anyone with such high credentials. Often I get an interest and learn on my own. You go to the store and ask questions. There are books to read and then you experiment, learning as you go. Of course your results may vary. After lots of projects you might get it right. Really, it is best to find a great teacher.
Singer 29k71 Patcher is a very versatile machine. The treadle stand is missing.
If you know this machine then you know how versatile it is, helping you out of tight spots. Old they may be, but they certainly do a great job at fixing up modern day clothing. While the design of these machines has varied little from the ~1910s the machines can be purchased new today with near identical designs.
It is not easy to use, nor is it easy to set up. The bobbin is small and has a very limited capacity. Threading of the bobbin requires some learning, as this is unlike other machines. What is the purpose of the long wire?
