Most drawing media either are dry (e.g. graphite, charcoal, pastels, Cont\u00e9, silverpoint), or use a fluid solvent or carrier (marker, pen and ink). Watercolor pencils can be used dry like ordinary pencils, then moistened with a wet brush to get various painterly effects. Very rarely, artists have drawn with (usually decoded) invisible ink. Metalpoint drawing usually employs either silver or lead.[25] More rarely used are gold, platinum, copper, brass, bronze, and tinpoint. A drawing instrument releases a small amount of material onto a surface, leaving a visible mark.<\/p>\n

The difference between a sketch and a drawing comes down to the level of detail and finish. A sketch is usually a quick observation, it is often the precursor to a final product. Use your finger or a blending stump to smooth out pencil strokes and blend them together. This technique is useful for creating soft transitions and realistic shadows.<\/p>\n
For this type of sketching, it is crucial to have a good understanding of human proportions (face and body). More often than not, body proportions are elongated in fashion sketching. For example, the total height of the human body in fashion sketching is 10, 11, or even 12 times the height of a human head as opposed to real-life proportions of only 7.5 to 8 heights of a human head. The most important aspect of fashion sketching is to be able to capture a design idea in the best possible light. Hence a facial-portrayal of a human figure is usually not significant. In this case, it is critical to be able to deliver the idea of the designed collection to the best advantage.<\/p>\n
