Take your pencil and paper and sketch the outlines of the letters. Use light pencil marks because these outlines are only guidelines that you will erase later. You can either sketch block letters (like the "H" in the photo) or print regular letters.
Using a thick-tipped artist's marker, begin drawing dots from the upper left-hand corner of your first letter and work toward the bottom right to avoid smearing the dots you have already drawn. For example, if you are drawing the letter "O," begin with a dot in the upper left and continue around clockwise until you meet up with your initial dot. Take your time to ensure that the dots are uniform in size.
As an alternative beginning, make a dot on the left edge of a letter and another dot on the opposite right edge. This will help you allocate the correct number of dots. Now put a dot at the halfway point between the two dots, which will create two new sections. Then put a dot at the halfway point between the dots bordering the new sections, and continue dotting like this until the border of your letter is filled in.
Eraser the letter guidelines. You now have only the dots remaining with no lines connecting them.
Take your marker to make any finishing touches on your dotted letters. If certain dots are too small, for example, make them a little bigger to balance the size of dots across your letters.
