Antique stained glass doors/windows

[FC]

I’ve got two large and two small antique doors/windows. First one, a small, is pretty much done. Originally had clear glass. No telling how much stained glass I broke! They’ll likely go in our living room cathedral ceiling windows.

Just an observation:  I can't see stained glass as being terribly good at insulation.  Now, in Central Texas, it is not as critical as North Dakota, but still, utilities will be higher.  Have you considered putting an additional layer of glass or plexiglass over it on the inside?  Or maybe even the outside, which would protect it from damage as well.

They’ll take the place of this hanging stained glass. They won’t be the actual windows.

That's a good way to do it.  You get the stained glass look without losing all the cool air.
