I always prewash and I use liquid starch. After I wash and rinse, I will put enough water in the washer and a quart of liquid starch. Swish with my hands and the spin dry. After taking the fabric out of the dryer when dry, I use a steam iron and the fabric feels like it has never been washed and the wrinkles disappear. At $3 for a jug at Wal-Mart, it's cheaper than Best Press.
