Sometimes when working with oil pastel on a toothy paper, you’ve got delicate color shifts that unfortunately don’t sink into the paper’s tooth. Generally applying a lot more oil pastel would be the solution; but that can sometimes ruin the original colors that were laid down.
Fear no more! Pilot’s FriXion erasable pens have rubber “erasers” (no more than a little rubber nub). These blend oil pastel brilliantly! The rubber nub for erasing (it’s called FriXion because it removes the ink via friction) never seems to wear down. Keep some newspaper handy so you can clean it off from color to color.
Dearest Pilot FriXion magic oil pastel blender, you’re now part of my art arsenal.
