With all the eating and drinking the festive season brings, you could be forgiven for falling asleep in front of the TV. But thanks to these special Netflix socks, you'll never miss another episode of your favourite show.
They detect when you nod off and hit pause. Genius.
You can't buy them in shops. Instead, Netflix has provided a guide on how to make them yourself at home, with a list of which components you'll need, and even knitting patterns for some of its best-known shows.
Fall asleep, and the accelerometer will detect you've stopped moving and pause whatever you're watching. Then when you wake up, you won't have to rewind and try to guess where you fell asleep.
Before they pause, a light in the cuff will glow to give you warning. If you're not falling asleep, just move your feet to stop it from pausing.
Knitting patterns include 'Unbreakable Kimmy Schmidt' and 'House of Cards'. You could even give them as a Christmas present to the Netflix addict in your life.
The socks are the latest Make It item from Netflix to improve your viewing. Previous devices include a Netflix Button which starts the streaming service and simultaneously dims the lights.
