Holiday Lights

This string of 5 "holiday lights" is formed from 2" x 4" bits of scrap glass, primarily water glass and glue chip.  The ends of the bulbs are small rounded rectangles in a grey/white streaky glass.  The "cord" is 2 pieces of 16 guage tinned copper wire twisted together, then curled and tacked to the end of each bulb.  Each set of lights is different, and brighten my windows without using any energy!
