Ah yes. I also bought my first pair of satin pillowcases from Bed, Bath & Beyond.

They were a decided improvement over the flannel that I'd been sleeping on before...but then, this past Christmas, my parents bought my satin sheet set (which included 2 pillowcases, naturally) from JC Penney and they were much higher quality.

But I tend to alternate between the Bed, Bath & Beyond ones and the JCP ones, depending on whether oil from my hair or skin has gotten onto them. Pillowcases must always always always be kept clean to help prevent breakouts.    So I'm always using one pair and washing the other.
