I saw a documentary of how they constructed the Basílica i Temple Expiatori de la Sagrada Família,
and the photo here reminded me of their stain-glass windows!

sorry I had to type Windows.....
I can see that, LOL.

That is a background consisting of two images, both half the width of the actual size. I duplicated both and flipped the one on the right side so the matched evenly in the middle.

First image…

You add all the other stuff (many more layers to this PSB document) in on top and it merges pretty well. The background just enhances things (like it should), rather than showing all the imperfections.

And to make this relevant…all work was done on a 2009 MacPro using Photoshop 2025 and earlier. The complete file is over 6GB.
