Merging socks
Who does not know this: socks that are only rolled up loose unroll again and the sock compartment is always messy. If you fold them completely into each other, so that one sock disappears completely in the other, the cuffs are thinning out.
It's a lot easier if you just put them halfway inside each other. Place socks on top of each other, put both cuffs together only a few centimeters from the inside out and let the rest hang loose. So everything stays together nicely, and it does not wear out.
