Hey BHP- I was kind of in your shoes about a month or two ago. Never sewn before, got a VERY quick lesson from a friend then got a Cowboy. I was ALL kinds of confused. This video helped immensely:
It does get better. Try to refrain from changing anything but the longer tension knob... I changed all kinds of things because frankly the instructions sucked. Now I can pretty much rethread, sew, pick up the bobbin thread, no problem.
I'm not on here a lot, but will add a subscription to this thread, so ask away!!
