hey all, perhaps this is useful. loading a bobbin is pretty universal, though your machine might be sort of different than mine, the concepts are the same.
first, put your machine in neutral- on my little engine that could, i have to pull the whole purple wheel out away from the casing.
then un thread your machine so the spool is just sitting on the holder. then, find the turning point. on my machine it's the thing that looks like a screw just to the left of the tension lever. pull the thread around that, and then back toward the spool.
next, you take the thread, and thread it into the bobbin from the inside out, pull enough through so there's a bit to hold on to.
then you put the bobbin on the holder (you might need to slide the holder to one side or the other), and use the food pedal to spin it. you need to hold on to the little bit you threaded through, so it will be tight enough, and you don't want to go too fast, because it might tangle or go all wonky.
