Abstract: Apparatus, kit and method for painting a marbleized pattern on an essentially flat interior surface using paints with a plurality of colors. Before beginning the process, if necessary, the surface is cleaned and prepared. This can include applying masking tape around the periphery of the area to be painted. Splotches of paint of one color are then applied to a portion of the total area to be painted using a stiff bristled brush. Splotches of other paint colors are then applied interspersed with the previous colors. The brush is then used to preliminarily blend the various splotches of paint. A special blending tool faced with wool is used to complete blending the paint. The wool face is moistened before use, and blending is completed by patting the paint with the wool face of the tool while changing the angles and locations of the tool between each contact. Accent veining lines can be added to the blended paint surface using a feather dipped into a paint of a different color than the blended surface.
