Generally, an image of the object has two coating lines, namely a line of light is used as a guideline to create the basic shape and the second object is a thicker line as a pointer.
make a line of light is to use subtle movements to generate a bit of pressure and traction. Light lines usually do not look so obvious and usually is often omitted when finishing or shading.
After creating a light line, then the next is to create a heavier line to determine the edges of the object element. Start by retracing the original line with movements and pressure gradually. Start with smooth and then add pressure so that the lines that were formed then seen more clearly.
