I also have a bunch from my grandmother that I inherited when she had to move out of her home. For years at Christmas all the granddaughters (5) got a pair of pillowcases she had embroidered.
I have done the dish towels for my daughters as they move out on their own. When using the white flour sack towels they dry dishes so much better.
Our WM use to sell them but they got rid of them along with the floss a number of years ago. Now I usually find them at Hobby Lobby or Joann's. For me it's an easy transportable had project to work on.
