I have loved Cathedral Windows since stumbling on a blog "Hyena in Petticoats"
http://hyena-in-petticoats.blogspot....-tutorial.html
I ended up buying a book "Through the window and beyond:New designs for cathedral windows " which gives instructions for machine and hand construction of cathedral windows. I am in the middle of other projects at the moment but have wrestled with the knowledge that these thing become very heavy so I am unsure what to make but will surely complete a cathedral window project some day.
