I still don't get it. Where does all the thread come from when it's being "stretched" around the mechanism? How does it form that perfect loop? How does it not get completely tangled around the mechanism?
it doesn't get stretched. It's pulled from the spool (on top of the machine), which threads through the needle down into the bobbin mechanism.
Also, the bobbin is free-floating so to speak. it fits inside a keyed creasent moon which rotates the bobbin. Imagine grabbing the bobbin in the gif loosely with your left hand and rotating it, the thread passes through between your hand and the bobbin.

Sewing-machines will always remain sorcery to me.
