The prompt I used for the Index Card A Day challenge day 56 was “Numbers”. I used a soft lead pencil to sketch outlines of each number 0 – 9. Then I used a black Uni-ball Vision fine point pen to go over those outlines. I used Prismacolor pencils to color the numbers, changing pigments when I came to where the numbers intersected each other. I used a black Prismacolor pencil to color in the background (those spaces where no number shapes were); furthermore, I left some white in the numbers. I loved the overall effect.
