I keep the manuals for my machines handy -- my Janomes have the threading indicated on them, but my old Elna does not. At church we have several machines and no manuals so threading is by the seat of my pants (always stressful). The worst is trying to remember how to wind the bobbin of the Singer that winds the bobbin in the top loading bobbin case. I don't do it often enough to remember -- and I never remember to bring the bobbin winder into church.
