You will find a box of pre-wound bobbins on the Bobbin Stand itself or on the storage shelf. If there are fewer than 10 bobbins in this box, please let the PoC know so that more may be ordered. Please do not use bobbins that were not purchased pre-wound on the Barudan.

Loading the New Bobbin into the Bobbin Case

Step 1: Hold the bobbin case with the front side down and the opening closest to your body.

Step 4: Bring the thread through the slit in the edge of the bobbin and under the tension spring until it comes out the opening.

Thread passes through the tension spring and then through the hole in the front of the bobbin case.


Step 5: Wind the thread through the metal pigtail on the front of the Bobbin Case.

The pigtail eliminates the need to push the end of the thread through; simply wind it through once.
