Question

see?
basically, to enlarge the image, youll need to do this kind of
math (even if you hate math!). its necessary in order to make
sure the enlargement is exactly proportionate to the original.
if youre not sure whether youve done the math correctly, just
count the number of squares in each row and in each column,
and ask yourself:

• are there an equal number of rows and columns on the

canvas as there are on the reference photo?

• are the squares on the canvas perfect squares, just

like the squares on the reference photo?

if you can answer yes to both of those questions,
youve got the gridding process down pat!

now, back to the 5\ x 7\ grid above.

i find that its sometimes easier to keep track of where i am
amongst all those little squares by marking them
numerically and alphabetically along the edges of the
paper and canvas. this way if i get lost, especially within a
much larger painting with many more squares, i can easily
locate where i want to be. i write the numbers and letters
really small and lightly, so that they can be easily erased. it
looks something like this:

1. according to the text and the images why is it

important to number the grid? it is important to
number the grid because...

Explanation:

The text states that numbering (along with lettering) the grid helps artists keep track of their position within the small squares, especially in larger paintings with many squares. It allows them to easily locate the area they need to work on, avoiding getting lost in the gridded space.

Answer:

it helps you keep track of your position among the grid squares, making it easy to locate where you want to work, especially in larger paintings with many squares, so you don't get lost in the gridded canvas or paper.
