Doodle doesn't follow any specific guidelines, it's an art which resembles more like a scribbling or following the same patterns. All of us have done our share of doodles right from childhood. Remember the boring physics or maths classes, where we let our minds wander and start drawing some funny characters on the paper? Doodle is all about drawing some funny things without any real focus on the characters. Doodle is an art which flows from the subconscious mind. If you want to get a real career in Doodle art, it would be wise to carry sketch pads, pens or pencils, since you never know when inspiration will hit you. Some of the most popular doodle artists are Jon Burgerman, Dennis Hwang, Les Paul, Tyrus Wong, Mario Miranda, Robert Moog and more.
