@CelloMomOnCars oh yes, I also just buy cotton, have for a long time, feels better. (Yes, it’s also not unproblematic, but then, what is.) I am unhappy that much cotton is only washable at 30°/40° though, especially for bedwear 60°C is a minimum IMHO (but synthetics aren’t better in that, and they do stink)
@mirabilos
Those washing instructions are there mostly to protect the manufacturer! Once it's mine I can see fit to wash it at any temperature. If it's really 100% cotton and the dye is good, you should be able to do 60C.
My sheets go in at 90C (I'm old fashioned) but they are all off-white.
