Dividing a segment line into equal parts

1. Draw a line from a vertex

2.Mark on it 7 equal segments

3. Draw a line from the 7th mark to the other vertex

4.Draw parallel lines passing through the next of the marks

5.The intersection with the segment defines the 7 equal parts

6.Same process can be repeated with any number of divisions

How to draw and enlarge an image with a grid (the grid method)

• you need to draw a grid over your reference image, and then draw a grid of equal ratio on your work surface

• the size of your artwork must always be equally proportionate to the size of the reference image

• you need to transfer what you see in the reference image, block by block, onto your paper
