Bottom of diagram 3 is where the confusion is now, since the shop lady threaded it differently than we were. I should really take a picture to show you the difference in how my supposedly correctly threaded machine differs from this part of the diagram. I appreciate your time and help. Your recent insructions are a little too technical for me at this time, as I don't even know where the feed dogs are
But, that is okay because the foot only wobbles if I push it and sewing straight is not a problem. What a learning experience this is!
Holiday Blessings to all.
