Step 5

Connect each pencil mark at the top of the picture with a corresponding mark at the bottom using a ruler. This will make parallel lines over the picture.

Step 7

Connect the marks on each side. Your picture is now covered with squares called a grid.

Step 8

Calculate how much larger you need to make your picture and how large you need to make squares on a second grid. For example, if you are doubling the picture size, squares in the second grid will be 1 inch.

Step 9

Draw a second grid on a larger sheet of blank paper. Use a yardstick to make this larger grid if necessary.

Step 10

Copy the picture from the first grid, square by square, by drawing it on the new, larger grid.

Tip

Reduce a picture by decreasing the size of the squares on the second grid using the same technique. If the size of the original grid is 1/2 inch and you want to make the picture half the size, make 1/4-inch squares on the second grid. Use this technique to enlarge or copy cartoon characters, coloring book pictures and lettering for signs.
