- The Bobbin could have tiny pieces of lint or dust on it causing a jam (highly likely seeing as I forgot that I even owned a sewing machine for the past 4 years).
- The Bobbin could have been inserted upside down.
- Or the tension settings were wrong.
I tried to start a third pillow but of course, I ran out of thread on my Bobbin. Once I refilled the Bobbin I then ran out of thread on my spool, and to be honest it wasn't worth the time or energy to go rifling through all my boxes that are packed for our big move! Monday we close on our home! Less than 5 days away!
