This 316L stainless steel thread falls somewhere between a thick thread and a thin yarn. Most sewing machines wouldn't be happy with this thread since its thick, and it has the 'furry' soft feel of yarn which makes it poor for most e-textiles/wearables projects. However, the high conductivity and softness make it a great thread for making telephone gloves!
Sew a couple inches into the pad of your gloves to keep your hands toasty while you use your phone, tablet or any other device with a 'capacitive' touch screen. Because capacitive sensors sense your finger through conductivity, not pressure, they don't work when you wear your gloves - they act as insulators.
