Thanks for asking...my client bought the four antique tin panels in New York, during one of her trips there. They are 24"x24". I'm not sure exactly which shop she purchased them from. Just Google "tin ceiling panels" for more information of where you can get them. We had them mounted together with about 1.5" apart using heavy plastic fish wire and screws. Then they were hung from the ceiling about 2" from the fireplace. We used hooks in the ceiling and more plastic fish wire from the two top panels to the hooks. We did hire a professional installer. Hope this helps...

thanks so much for the detailed info! The room has such great attention to detail, yet it looks livable & relaxed. And I love the 4 tin patterns grouped together. I may try to imitate them on canvas with some gesso for texture. The top white one reminds of a 20's bungalow leaded window. I'll look for more posts from you!

Thank you so much.
