Usually, white acts as a background: a blank canvas invites color and line, and a blank sheet of paper is quickly layered with ideas and sketches. For once, try letting white take center stage! Drawing with white ink on a dark paper surface may be a challenge, but when done successfully, the results are stunning.
Opaque white ink can also double as correction fluid, which is incredibly helpful when you accidentally color over your negative space or need to fix tiny details. Many artists use it to add highlights to their comic art!
