There are so many benefits to silk pillowcases. They are hypoallergenic, don't wick moisture from your face, don't drag your skin or hair when you move and make you feel special. They are easily laundered on the gentle cycle and while my washer and dryer are fairly new with no snags etc in the dryer or washer I put them inside another regular pillow case cover that snaps closed or wash it with other clothing requiring a delicate setting. While this may seem like a lot of extra work it really isn't. I sleep better and more soundly with these pillowcases and hope some day to buy the set of sheets. These pillow cases get twelve thousand stars.
