These are not fabric. They are made out of the tough disposable paper that some envelopes are made of. They also make noise when you move your head on the pillow. I think that they must be meant to be disposable. Terrible.
Looked in so many stores and couldn't find what I wanted, went on Overstock.com and there they were and I love them. They are used to protect my down pillows and the pillow cases slide over them so easily! I would highly recommend this product to anyone in the market for new Pillow Protectors.
