but Margo... you are co-ordinate... while I am a total klutz and dropped the screw... it is easier to have a second bobbin case just in case .... The original can stay as it was when you bought it.
Tiny adjustments on the bobbin case can make a huge difference! Think of the screw as a clock face, and only turn it in 5 minute increments, checking the tension each adjustment. (You can also work over a magnetic bowl or terry cloth towel to catch the screw if it does come out!) I have several machines and would lots rather buy more fabric than spend that money on extra bobbin cases!!
