Applying media

Prior to operational on an image, the performer will likely want to gain an understanding of how the a variety of media will work. The dissimilar drawing implements can be tried on carry out on sheets to see what type of blueprint they create, and how to apply the put into practice in order to produce varying tones.

The stroke of the sketch implement can be used to control the appearance of the image. Ink drawing typically use hatching, which consists of groups of parallel lines. Cross-hatching uses hatching in two or more different directions to create a darker tone. Broken hatching, or lines with alternating breaks, is used to form lighter tones, and by controlling the density of the breaks a graduation of tone can be achieved. Finally stippling, or random placement of dots on a page, can also be used to produce a texture or shade.

Sketch drawing use similar techniques, though with pencils and drawing sticks continuous variations in tone can be achieved. For best results the lines in a sketch are typically drawn to follow the contour curves of the surface, thus producing a depth effect. When drawing hair, the lines of the rough draft follow the track of the hair growth.

Typically a drawing will be filled in base

on which hand the artist favoritism. A right-handed artist will want to draw from left to right in order to avoid smearing the image. Sometimes the artist will want to leave a section of the image clear while filling in the remainder of the image. A frisket can be used for this purpose. The shape of the area to be preserved is cut out of the frisked, and the resulting shape is then applied to the drawing surface. This will look after the surface from receiving any stray inscription before it is ready to be filled in.

Another method to conserve a section of the image is to apply a spray-on fixative to the surface. This will hold loose textile more firmly to the sheet and prevent it from smearing. However the fixative spray usually uses chemicals that can negatively affect the respiratory system, so it should be employ in a airless area such as outside.
