Use a blank sheet of paper and look for surfaces with different textures such as wood, cement, flagstone, grating and others. Place the paper onto the chosen surface and colourt it with Faber-Castell crayon. Try to use the crayon in the horizontal position and check the range of effects that you can get.
Using Connector Colour Pens, you can colour in your drawings with parallel lines to get a different look. By placing the lines closer to each other you can add intensity and shadow to your drawings.
You can get shadows as well as a dimensional effect by using different shades of the same colour on different parts of the drawing. The closer the lines are together, the darker the shade. The further the lines are away, the ligther the shade.
To draw curved objects just colour your drawing using bent lines.
You can also colour your drawings with dots. By changing the space in between dots, you can get shining and lighting effects. The best product to colour using dots are Faber-Castell Poster Art Pens, because they have bigger tips.
You can create new colour with dots by drawing dots of different sizes, densities and colours. This can give the appearance of a single colour when viewed from distance.
