We carry this thread in 2 and 3 ply. 2 ply is a little thicker than every day polyester or cotton thread but still thin enough to be sewn by hand in medium-eye needles or with a sewing machine that can handle 'heavy' thread. Because it is strong and smooth, its ideal for any wearable/e-textile project. It also has fairly low resistivity, 16 ohms per foot so you can use it to drive LEDs and other electronic components that use under ~50mA.
Our 3 ply thread has a resistance of 10 ohms per foot for components that use under ~100mA. It is thicker than standard cotton/poly thread and can be used by hand or in industrial sewing machines.
Because it is made of stainless steel fibers, it will not oxidize like silver does: your projects will not 'stop working' because of oxidation after a few months and its safe to wash. However, this thread is a little 'stiff', it feels a little like 'waxed thread' and is not ideal for making iPhone-compatible gloves. If you want to sew conductive thread into the pads of gloves, check out our thin conductive yarn!
