The picture I linked is of a buckwheat pillow. Had no idea they were a thing before today.
What about silk or bamboo pillow cases?
I’ve only ever really used cotton pillow cases and cotton stuffed pillows. I recently upgraded to a foam pillow that I’m enjoying.
I love my husks in a sack. I also use a foam pillow here and there, tried a hyped up shredded foam pillow but hated it, solid foam is the way for foam imo. Never tried silk pillow cases but I do enjoy cotton.
