How do you keep threads from splitting?
Set the tension to the best thread tension setting or less. Make sure the spool of thread is installed correctly using the correct size spool cap for the size of spool. For details, refer to “Place a spool of thread on a spool pin”.
How do you fasten a thread?
This way of anchoring the thread can be a bit more visible than a knot when the seam is pulled flat, so try to keep this style of tying off slightly in the seam allowance if you can!
