Video: How do you put away your socks? You probably roll them, right? Perhaps with the Army Ranger roll? Folding your socks into origami-like squares might be more space-efficient. The video above posted by YouTuber Klara Egilson shows you this new sock-folding technique. Basically, you lay the socks perpendicularly to each other and fold and tuck them into each other. This not only prevents the stretching that happens with the rolling method, it makes organising your socks a little easier, since you're dealing with flat squares rather than balls. I imagine this is how Marie Condo tidies up her socks.
This method doesn't work for short socks, unfortunately, and it does take more time, but it also looks kind of fun — as far as you can connect "laundry" with "fun".
