Our online glass photo's are meant to give the stained glass artist a general idea of the color and texture that you would receive when purchasing glass. Please note that every sheet of glass is unique and therefore the images you see should only be used as a guideline. Also, computer settings such as the gamma setting on your monitor and the amount of display colors on your video card may alter the colors of the images on your screen. When calculating quantity needed, please keep in mind the sizes (where listed) are approximate, due to variations in production
