Grids can also be considered bases in origami. There are various types of grids and various ways to fold each type. There are, for example, relatively simple 2 by 2, 4 by 4 or 8 by 8 grids, but also 7 by 7, 10 by 10 and so on.

Tip: If, for some reason, you need a grid such as a 5 by 5, 6 by 6 or 7 by 7 grid, fold the grid in whichever way you prefer, then tear or cut off the extra rows of the 8 by 8 grid.
My thanks and appreciation to Ilan Garibi for teaching me this very useful technique.

You might ask why one would need to fold a grid?
Grids may be folded for various reasons, such as:
* simply to make a pleasing pattern on a sheet of paper in an art class;
* to prepare for folding a tessallation, a type of origami that makes repeating patterns on paper;
*  a grid could be part of a frame for a photo or the lid of a box;
* some origami models rely on first folding a grid in order to fold the actual model.
* folding and using a grid is an excellent educational tool in subjects like maths, science, economics, art and in general, actually.
* since in origami the grid is tactual, it is especially helpful for students who are blind or visually impaired
* you could play a game on a folded grid. This is particularly helpful when you are blind and want to play games such as naughts and crosses or dice games where you have to jump from block to block.
* A grid can also be used for art activities for blind or visually impaired children, including folding, cutting, coloring, etc.

Keeping the above variables in mind, the descriptions below should get you started on how to fold some basic grids.

The instructions below are for an 8 by 8 grid folded using a square, meaning the square will end up having 64 blocks of equal size.
 If you have done accordion folds or bases, folding a grid is somewhat similar, except that where the accordion folds usually create panels or lines across the paper, a grid will be folded lines in both directions, thus creating blocks across your paper.
Put in another way, you will only need to know how to make seven horizontal folds for this grid.
You will then simply turn your paper 90 degrees so all your lines would then be vertical (running from top to bottom).
The same seven folds will then be repeated with the square in the new position, which will produce a very accurate grid.

Keep in mind that the instructions below are very detailed, so might seem tedious the first time you fold a grid. If you are a beginner folder or just want a systematic way of making pleats or grids, try the instructions out a few times. Once you understand the sequence and method of folding you won't need them any longer.

Paper used: Square
1. Place your square down with its edges left and right, top and bottom.

2. Valley fold the bottom edge up to meet the top edge.
Crease and unfold.

3. Valley fold both top and bottom edges to meet the center horizontal crease line.
Crease and unfold.
Result: You will have 3 valley creases now.

4. Repeat the previous step, but now fold the top and bottom edges in to meet the first crease lines from the top and the bottom.
Crease and unfold.
Result: You will have 5 valley creases now.

5. Take the bottom edge and fold it upwards to meet the second crease line from the top.
Crease well and unfold.

6. Take the top edge and fold it downwards to meet the second crease line from the bottom.
Crease well and unfold.
Result: You will have 7 valley creases now, dividing your square sheet into 8 long panels.

7. Turn your square 90 degrees to the left or right, so that the crease lines now run vertically or from top to bottom.

8. Repeat Steps 2 to 7, forming another 7 creases that will divide your square into 64 small blocks.

If you count from the top block on the lefthand side, the first row will contain 8 blocks. Similarly, the row on the left will also contain 8 squares if you count from top to bottom.
Make sure that you can clearly feel all the grid lines. If you find that some lines seem faint, make a valley fold to accentuate these vertical or horizontal lines.

Your 8 by 8 grid is ready for use.
With thankful acknowledgement to Nishi Sakpal for her instruction and help with compiling this document.



To fold an 8 by 8 grid across a square or rectangle, you can also use accordion folds.
To use this method, first fold your square or rectangle by using the instructions on this page.


You will then simply turn your paper 90 degrees so all your lines would then be vertical (running from top to bottom).
The same seven folds will then be repeated with the square in the new position, which will produce a very accurate grid.
