Sew a couple inches into the pad of your gloves to keep your hands toasty while you use your iPhone, iPad 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.
