Abstract: An instrument for making graphic designs on walls or ceilings, including an elongated member having a plurality of rigid sections joined together by a unitary, integral flexible portion, center-line apertures spaced along the longitudinal axis of each rigid section providing a pivot point and a plurality of marking points along the instrument, each section having paired edge apertures spacially located along respective, opposite longitudinal edges of each section, and a paint pad having a pair of upstanding lugs for detachably mounting the paint pad at a selected pair of edge apertures to selectively place painted arc segments or stripes on walls or ceilings. A guide member having rollers can be mounted to one end of the instrument to aid in placing vertical or horizontal stripes on walls or ceilings. For very large wall or ceiling surfaces a link member can be used to couple together two instruments.
