The device comprises a casing composed of a bottom tray having an upstanding pivot post and a hinged cover having an open window. Three concentric flat rings have partial designs embossed thereon to provide raised design portions, the inner ring being rotatable about the post, the intermediate ring rotatable about the inner ring and the outer ring rotatable about the intermediate ring. By individually rotating or angularly positioning the rings relative to each other, any of the partial designs can be radially aligned to form a composite design. After the composite design has been formed, a piece of paper is placed over at least the segments constituting the preselected design. Closing of the cover on the tray clamps the rings in a fixed relation with each other so that the user can then rub a marking implement, such as a colored pencil or crayon, over the portion of the paper appearing in the open window in order to transfer the preselected design onto the overlying paper.
