Soleil is the French word for sun. "So-lay" sounds like the sunny south of France where they grow the flowers for the perfume industry. 7.5" rounds of glass are slumped over my original sun face tiles to create these whimsical discs of color. They are available in 12 colors and over 20 designs. They can be hung from a ceiling, in front of a window, or outside in the garden. The 18" long Kevlar fish line is nearly invisible and extremely durable; a 7" long brass hanger is also included. The brass hanger is for indoor use and will keep the sun face parallel to the window glass: no twisting and turning.
