A progressive stencil set apparatus produces complex stencil drawings. The set comprises a plurality of sheets of a stiff transparent material, each of the sheets providing at least one aperture. The aperture in a first one of the sheets forms a portion of the complex stencil drawing. Each further stencil sheet is laid down on top of the preceding one until the entire drawing is completed. Cross-hair alignment is facilitated so that the sheets are always positioned correctly.
