There's still the stand-bye fabric paint. They have very fine tip bottles of it that you can use to write directly on the fabric. You have to let them sit for 24 hours without touching them and then heat set them with a warm iron (on the wrong side). I would practice writing each name on a scrap first, and make sure not to touch them until they are completely dry. This is what I use to write names on my Christmas stockings. You can find them about anywhere you can find crafting supplies, including WalMart, some Big Lots Stores, Hobby Lobby, Michaels...etc.
