I just spent $24 at a local charity thrift store on slightly used top sheets. I will be able to make at least 20 Princess Pillowcase dresses out of them. Most people must be like my husband who refuses to sleep under a top sheet. I always find a few of them everytime I go to that store. I stay away from the ones that are mostly polyester. The ones that have just a little are good because they look good after laundering without having to be ironed.
