Today, the WWF is teaming up with grannies nationwide for National Sweater Day—a day to raise awareness about energy conservation. Led by spokesgranny Gladys, in her poinsettia-patterned knit, the campaign is meant to persuade the thermostat-inclined (guilty as charged) to don a sweater and turn down the heat. As Gladys says, grannies are “natural energy conservers” who put on a sweater when they get cold. And as we learn in the hilarious campaign video, you can sign up to receive a phone call from an on-staff granny who will nag gently remind you (as grannies do) to turn down the heat. We’ve picked our favourite knits to help you conserve energy for the day.
