Oh this is the easiest!
WASHCARE INSTRUCTIONS
1. Turn your Satin Pillowcase inside out.
2. Wash in cold water on low spin cycle.
3. Hang out to Dry. No Tumble Dry.
IRONING
To Iron your pillowcase, I suggest placing a thin cotton sheet over your satin pillowcase to iron. Never iron directly on your pillowcase as it will technically melt the fabric.
That's it!
