Markers are an amazing and very versatile tool but are sometimes under appreciated when it comes to drawing and sketching. This is the first in a series of books especially written for the e-book devices which will teach rendering and marker techniques. This book focuses on the concepts on how to use markers and how to create metal shapes using those markers. The book contains step by step examples of how to create the metal looks for brass, stainless steel and aluminum from refrigerators to lamps. The book also contains many finished examples and photographs as real world examples to draw from. This book is enhanced for e-book readers with color screens. About the Author. Donald A.
