This is the type of white cap I wear. Usually, I make more of an effort to get my hair under it, but it was the end of the day, and the loose bits were coming down. I found new ones this week on eBay. Lucille’s Sweet Memories, out of Ohio, often has some, and she had a few more in stock, and I found one more at auction, so I bought it.
It is a light, gauzy fabric, bonded, with linenfold pleats embossed into the back. The ties are narrow grosgrain ribbon. I assume that this is the kind that Mennonite or Amish women wear in Ohio. I haven’t spent any time there, so I can’t speak from experience.
