his video was very informative and exactly how I test my tension, my only difference is instead of a pin to clean out the lint on the bobbin finger, I uses a slip of paper....thinner than needle but does not invade that area, just cleans out any lint--and there usually is a dot of it..........
Off topic......why do men nowadays insist on wearing grunchy baseball caps everywhere, at all times...........I really want to rip them off men's heads when I am eating in a restaurant and I see one........My son in law tried it once in my house.......doesn't do it any longer...removes hat at door.....I was raised that way...I guess I really am old-fashioned.....Now I am beginning to see women do the same thing.....wearing a "hat" that much will cause hair loss...........not "hide" it!!!!!
