We know something, Jon Snow.

Turns out, the thick fur wraps worn by the men of the Night’s Watch as winter has come to “Game of Thrones” are actually repurposed rugs from the Swedish furniture giant.

Michele Clapton, costume designer on the HBO hit, revealed this wardrobe trick in a Getty Museum chat in Los Angeles last year that’s resurfaced online this week. “These capes are actually IKEA rugs!” she said, to audience applause. “We cut, and then we shaved them, and then we added strong leather straps.”

Clapton and her team also distressed the cloaks to look aged, which is called “breakdown” in the biz, and often includes using dye or sandpaper to achieve that weathered look.

“Breakdown … is like a religion on ‘Game of Thrones,’” Clapton added. “We want the audience to almost smell the costumes.”

Now the internet is playing “which carpet matches the capes?” with the Ikea catalog, with most guessing that the either the $29.99 white RENS sheepskin rug, the $49.99 gray SEJLING sheepskin rug, or the $14.99 faux fur TEJN. The white, fluffy floor coverings look like real fur, and can be easily dyed to look like wolf pelts.

And these don’t just make dashing caped crusaders. Some other lifestyle hacks for these shaggy rugs include turning them into plush seat cushions by attaching them to benches or stools, creating furry desk chairs Cruella de Vil would love, or sewing a couple together to make plush pillows or long floor runners.
