Use cotton yarn (#80-#120) to wind your own
bobbins. You can also buy pre-wound bobbins in
cotton or polyester for use in your SWF machine.
Insert the bobbin into the bobbin case. Holding the
bobbin case in your left hand, place the bobbin in
the case with the thread coming out in a toward the
right. Pull the thread across to the left under the
thread guide and pull it into the slot. Make sure the
thread pulls smoothly from the bobbin.
Trim the thread to 3-4 cm before inserting the
bobbin and case into the hook assembly. Long tails
can cause the bobbin thread to tangle when the
machine begins to stitch.
