When was the fitted sheet invented?
As I was 'folding' one today I tried to remember the first time I did this and when fitted sheets were invented. Google didn't help. Wikipedia didn't help. Any help?
(I know fitted sheets have been around for a long time. I remember a hilarious evening around 1950 when I leaped into a bed that had a *nylon* fitted sheet...and slid right out the other side, onto the floor.)
