Three notes and a treble clef  make this great stained glass pattern for the classroom or the teachers studio, or a great gift for that really good music student.  A bass clef is included at the end of the pdf file in case you want to substitute this for your studio, or maybe make both.  Three patterns in this purchase.  Two different sizes of treble clef and one bass clef.  (only one is pictured here, the other is pictured at gospelglass(dot)com).
