I used a silk nightgown of my mom's to make these items for my sister. Here are instructions I've published for the eye mask. For this one, I added a layer of brown felt to help block the light. I also used elastic lace (originally bought to make baby headbands) instead of elastic. I can't find the pillowcase instructions I used, but it was really just two rectangles sewn together. I used the existing hem of the nightgown for the hem on the pillowcase.
