That is most definitely so. Come to think of it, my aunt who is 30 years older than me mentioned this method when I was a teen. She and her husband were a piano duo who gave a lot of concerts and thus traveled a lot for work. So she really needed to develop a method of keeping her clothes wrinkle-feee living out of a suitcase. So that was in the 1980a. Marie Kondo is not old enough to beat that. Of course I do not imply that my aunt invented the rolling method but that it was known back then.
