Sewing machine problem !?
 
                My sewing machine (e&r classic nt21 model) is not picking up the thread from the bobbin atall I have changed the needles several times, re threaded the machine checked that the bobbin case is inserted correctly, changed the direction of the needle and cleaned the machine, I can't think of why it won't stitch ... Help !
