Sew traces with conductive thread and red or black bobbin threads to indicate the electrical polarity. Adjust the tension allowing the bobbin thread to pull thru to the fashion fabric so that the polarity is easily determined. Reverse side of the fabric clearly shows the bobbin thread. Keep bobbins wound and ready for action.
