Dr Nip said it well, but I use a couple of more tools than he showed. A threading loop for the bobbin, a bodkin with a sharp, hardened point, and I have 4 bobbins. Some are set looser for finer thread, others tighter for the bigger stuff. A good white light also helps me see what I’m doing, I use an ott light that I robbed from my wife. A good vise is a worthwhile investment that if you buy right and take care of it, you’ll hand down to someone.
