this is a light box, i took an average shadow box, and put polymer clay on it, No this is not a real stained glass piece, but it does resemble stained glass. I use LED lights to help illuminate the image. I loved making this one, it killed my fingers but other than that the pain was well worth the results, Each piece of clay is hand formed on that glass on the box. the clay is MM thick instead of being precut and fitted for the picture.
