(Stainless Steel Thread for Sewing Circuits: Conductive thread is a great way to connect circuits in textile and craft projects. This thread is spun from stainless steel fibers, which makes it suitable for soldering as well as sewing. Can be used for hand or machine sewing - conductive thread should only be used in the bottom (bobbin) thread when machine sewing.This thread is somewhat "hairy" and thicker than typical cotton thread. It will behave similarly to embroidery floss. Resistance: 28 Ohms/ft)
