Stained glass and stained glass mosaic is a true workshop art: No part of the process can be automated or shortcut. Every piece of the artwork has the touch of the artist's hand and the light of the artist's imagination.  
Creation of a new work in stained glass begins with an original idea, typically much smaller than the eventual final work. In the image at right, the original for the Twin Sisters was a photograph. The section shown is approximately 3.5 by 3.5 inches in the original print.  
From the original, a full-size working image is created. The original is resized photographically, by scanning, or by pantograph. In the image at right, the yardstick provides an indication of scale. The working drawing has been pasted up in segments from reproductions of the original. The working drawing is now about 600% larger in each dimension than the original.  
In this image, the original photograph has been scanned and resized; in this case it has been scaled up significantly. The image shows about 1 foot square of the final full-sized reproduction.  
Whether the original was a drawing or a photograph, the full-size working drawing is now reproduced as a cutting master. It is on this cutting master that the decisions are made about the shapes and sizes of the individual pieces of colored glass. Image 4 at right shows a section about six inches square from a cutting master.  
Here is a work in progress, just one or two square feet of a work of tens of square feet. Individual mosaic tiles are being selected for color and cut to size and shape to bring the image to life.  
In this image we see a close up of a few square inches from a completed work, in this case the Office Logo. Notice that even in a work of mosaic, the glass pieces are not simply squares, but are shaped as needed to represent the total image.
