Cloak of Invisibility Technique

This jutsu allows a ninja to take a cloak or a piece of cloth and blend into an object, making them invisible. Konohamaru uses this technique constantly in the beginning of the series to try and fool Naruto Uzumaki, but uses poor disguises (square rocks with eyeholes, cloaks that are incorrectly patterned or rotated the wrong way around, or simply not covering himself completely), thus betraying the illusion. Naruto would later use this technique to try and hide from Ebisu.
