Stained glass windows are a bit like tattoos, once you get one you want more! I have just installed these two panels for a customer who I made two big panels for a couple of years ago. This happens surprisingly often, its great for me as I already know the customers and repeat customers are the best advert for my 
business.
These panels are fixed in front of the UPVC panels, I use this method regularly as most houses now have double glazing.
It was a wet and very dark morning, so the panels are brightening up a grey day, I will re photograph with the sunlight streaming through in the summer.
