Stained glass portrait

This stained glass project is being done as a gift for my dad. He has just had his 90th birthday and I wanted to do something really special for him. As a young man, an artist friend painted a beautiful portrait of him which I grew up admiring, so it's a real thrill for me to do this for my wonderful dad.
The technique being used is called appliqué and differs from normal leading or copper foiling in that the glass pieces once cut are bonded to a sub sheet of plain float glass.
