Correction fluid, originally named "Mistake Out" by its creator, Bette Nesmith Graham, is a critical supply for the workplace and home office. Thrifty individuals can create their own version at home following the original mixture recipe made by a secretary, which she used to conceal her typing mistakes in the days before errors could be deleted with the press of a button. Homemade white-out is inexpensive and can be tinted with a few drops of colored paint to match any shade of paper.
