I have a Brother VX-1120 I was sewing on some burlap and all of a sudden now the thread will not pull up the lower thread. Does anyone know what to do i'm lost.
Remove the bobbin and clean the bobbin compartment and holder.
Then re-thread the machine anbd re-install the bobbin.
that usually works
If that doesn't work, change your needle.
