Note: If the bobbin is installed correctly, it turns clockwise when the thread is pulled.
Preparing to Quilt
7. Test the tension of the bobbin case every time bobbin thread is changed; bobbin tension is the
foundation for correct thread tension.
a. Place the bobbin case on its side, on your palm.
b. Pull up on the thread. The thread should run freely and the bobbin should rise into a vertical
position without lifting off your hand.
• If the bobbin case remains on its side, there is too little tension. Turn the
large screw
(shown below in blue) clockwise.
• If the case lifts into the air, there is too much tension. Turn the
large screw
(shown
below in blue) counter-clockwise.
