Mittens and gloves keep your hands warm (barely), but they trap your fingertips, making motor control and touchscreen interface almost impossible. Fingerless gloves are the easiest solution, and slip stitch hand warmers are the perfect example. This intermediate fabric pattern can be a little complicated around the thumb, but your icy hands will thank you later for these knitted warmer when the cold of the night returns to your room and you’re still surfing the Internet or reading a book.
