It's part of the design process that, as you learn more, you revise what you previously decided upon.
I was recently on another set designer's stage where a lucky dumpster find of handsomely upholstered curtain pelmets threw every other decision into question. (Pelmets are hard to describe: kinda like curtain "hats"? Box-like-things-at-the-top-of-the-window? That's an awkward phrase.) This found curtain thing was so cool it just demanded to be used!

I too have been known to rework a design to use an unexpected fun-thing. Or - on the dark side - to change all a set's colors to suit a wrong-sofa. Just as I once did to for a great sofa on this same stage. (Sofas!)
