My parents gave me a goosedown comforter for Christmas. With that atop my layers of blankets, they assure me, I’ll never be awoken by the cold again.
The feathers — or parts of feathers — must be allowed to clump, it seems, but not too much. “Made up of light, fluffy filaments, the down clusters expand and intertwine to form air pockets” within cells of cotton cloth known as baffle boxes, says the description on the packaging.
Electric blankets have never appealed to me; I love the idea of maximizing the body’s own heat. I like to imagine that they were snow geese whose breast feathers will be keeping me warm, though I’m sure they weren’t.
UPDATE: Yep, it’s warm!
