Step 4: Threading of the bottom thread through the plate: Part One
Just drop it back into the hole so that the thread will unwind in a counter clockwise fashion. Make sure you hold onto the thread itself as you will need it to rethread the machine.(Picture 2)
Now look for a notch towards 6 or 6:30ish around the hole.(Picture 2) you need to place the thread into the notch and under the metal piece there. Now just pull off about 3 or 4 inches and pull it off to the left.
