If I remember correctly, the name is "nainsook." My spelling may be off, of course. When I used to make my own ties, I got the fabric at Hancock's. Since they are gone now, I would recommend finding a specialty fabric center that would carry more designer fabrics. The first one that comes to mind is High Fashion here in Houston. I don't recall seeing the fabric at any of the JoAnn's or Hobby Lobby stores.
