lot vintage cotton pillowcases w/ fancywork embroidery & crochet lace edging

Lot of five pairs vintage all cotton pillowcases with hand stitched embroidery and / or and crochet lace trim.

These are all nice soft fabric without a lot of wear, thinning or fraying, but they've been used and do have some spots and yellowing.

The pillowcases with the pink and white crochet have some weird spots which I think are probably from laundry blueing?

I haven't washed or soaked any of these, they're all as found right out of a farmhouse here in rural Wisconsin.
