This is a tremendous undertaking in stained glass but so fun. In all the patterns I have made I have never felt that a color file was necessary but in this case using the colors that were originally used by Goudi, for this wildly ornate cathedral glass and architecture is really quite necessary. The color gradations from the small round outer windows and the tear drop individual windows within, and the center (which clearly looks like the holy family in abstract, is so subtle that I could never reproduce this effect.  I can provide an enlarged (50 inches (which even then is too small)) pattern and a small color and black and white file as pdfs... which you can have your print shop enlarge.    I have posted the individual parts of this enormous pattern also... and the small circular outside parts are just totally fun.  This pattern is available on Gospelglass.com as well and as always, free to any place of worship, just ask first  HERE
