Calorimetry

Description from Knitty.com: > Calorimetry is a scientific term describing the measurement of heat lost or gained. > > Knit hats are a wonderful way to block out the cold, but when you have long hair it usually requires wearing it down, not often the most comfortable option on a blustery day. This headscarf allows you to wear your hair up while keeping your ears warm and preventing heat from escaping from the top of your head. > > My friend Meredith wears hers all around San Francisco and is modeling it here on the Big Sur coast. This can be knit quickly for a last minute gift, and as it only requires one skein of yarn you can afford to knit one for all of your friends.
