Designers can use Sketch to explore multiple or complex ideas without software distractions and complications. The same thumbnail sketches or scratch paper can be used to quickly refine and generate the idea on the computer in a mixed process. This hybrid process is as useful as logo design, in a software learning curve that can detract from the creative thought process. The traditional design/computing production hybrid process can be used to unleash one's creativity in page layout or image development as well. In the early days of computer publishing, many "traditional" designers relied on computer whiz production artists to produce their ideas from sketches without the need to learn computer skills themselves. However, this practice has become less common, especially since desktop publishing. Computer use and graphics software textbooks are used in most design courses. At the same time, many designers utilize a wealth of online tools and resources including color pickers, fonts, decoupage art and tutorials.
