The made to measure blind company, English Blinds has a set of designs that they promise will keep your home safe from White Walkers. Well, White Walker free for 10 years, that is. Come year 11 you’ll have to fend for yourself.
Sadly, the Game of Thrones inspired blinds don’t seem to be for sale. At least the Dragonglass infused designs are available from prices starting from 3 gold dragons and up and I can’t find any.
