First, carefully remove any grease marks from the glass, then, using a very soft brush, paint it with special paint for glass. The stem of the dish is given two coats of paint, while the sides are just lightly colored. When the paint has dried, the pieces of napkin that have been cut out (blue butterflies and little blue flowers) are glued on, using the normal glueing technique of spraying the back of the design with glue/varnish.
