Here is a wonderful short video from ESAG members John and Laura Gilroy. They are professional stained glass makers in the old school traditional way.
You can find their website here.
A note from the Gilroys on the following video:
"Portraiture in stained glass; hand painted with just brushes and the point of a needle - old school.
The portrait is of Fr. Paul Wattson, founder of the Franciscan Society of the Atonement, and is part of a 110 square foot window we are creating for St Joseph the Worker in Richmond.”
