In step three I scanned in the numbers to the computer. Then I took the jpgs into my Illustrator program. In the Illustrator program, I redrew the numbers using the sketches as a base to copy. Illustrator creates line art, not paint art. This line art is called Vector art. So I "vectorized" the numbers. The cool thing about Vector art is that I can resize an image without losing any quality. In a paint program, I am likely to lose image quality if I tried to upside the image.
After I redrew the numbers, I then printed them out, and checked that all of the number parts lined up with each other.
