The point of invisible writing, or ‘‘writing blind,’’ is to free writers from the urge to evaluate and revise their writing as they draft and to encourage them to let their ideas flow. You can try invisible writing at the computer by turning down your monitor contrast, or you can try it with pencil and paper. To work with paper, you will need two sheets of notebook paper, one sheet of carbon paper, and a used-up ballpoint pen. Place the carbon paper between your two notebook pages. Use the empty ballpoint pen to do your writing. Although you cannot see what you are writing as you write, when you look at the second notebook sheet — the one beneath the carbon paper — you will see the results.
