Completed August 2009. My largest mosaic project so far: ©2009, Silva Hayes, River through the woods These stair risers are mosaiced onto Plexiglass rectangles with a hole drilled in each end of each one. The risers were installed after all the work was completed. The mosaic is a mixture of stained glass, vintage jewelry, broken plates, and various bits. Little children love to slowly climb them and point out snails, fish, butterflies, dragonflies, and turtles that live near the water.
