The artist studies are my sketches as I start a piece. I just sketch with glass. I start with my photographs and first do a pencil drawing. Then to figure color combinations and light/shadow dimensions I create the glass sketches. These range in size from a 6″ x 12″ to a 9″ x 18″ or variations of this scale. I focus on the faces but also can include ears, noses, feet, spots — all to give me information for my large fine art pieces. If I need additional information I then do a miniature vitreous painting giving me more complete information.
