This arched leaded window shows how stained glass is so perfect for non-standard sized windows. This window serves to block a lot of light coming into the child's bedroom. I would have loved to grow up with a beautiful stained glass window in my bedroom! I used all opalescent glass from Kokomo and Uroboros glass companies and used accent of rondels and jewels. The window measures 35 wide by 11-1/2" in the center.
