ABSTRACT:
An improved design drawing device for drawing amorphous patterns is disclosed. The drawing device contains a segmented flexible guide comprised of segments covered with a soft plastic or rubber or rubber type surface piece. The segments each consist of a male ratchet and a female ratchet, which snap together, wherein the size of the designs created are determined by the number of segments used to create the design. When the segments are attached together, they ratchet relative other so as to lock their positions in place. The drawing device also comprises at least one solid wheel disk which is rotatable about the inner circumference wall of the segmented flexible guide, and at least one hole through the solid wheel disk through which a drawing implement is positionable, wherein the solid wheel disk is rotatable about the inner circumference wall or outer circumference wall of the segmented flexible guide when the drawing implement is positioned through the hole positioned through the solid wheel disk, thereby forming a patterned drawing. As the wheel disk revolves around the inner surface of the segmented flexible guide, the teeth of the wheel disk enter the surface of the segmented flexible guide at right angles to lock into the surface of the segmented flexible guide.
