5. Tips for sketching
Use your pencil lightly at first, then darker once you are sure of a line’s placement
Not always drawn to scale
Use your space – fill up the paper you are given. Smaller sketches are not better sketches
Correct proportions are imperative (check regularly)
Height, Width, Length
Measure with your pencil

6. Steps to create a straight line

Keep your eye on the point where the line will end
Draw light lines between points
Darken the lines to create to create a continuous line
Your eye leads the pencil along the light sketch line

9. Contrast When shading, contrast is very important
Contrast – the state of being strikingly different from something else
This means the darkest part of your sketch should be VERY dark, and the lightest part should be left white.
