Finally I pulled it all together today! I'm very pleased with the results and have a sense of satisfaction.
I knew I had to spray paint the new arches, and went on the hunt for low-odor spray paint, as it's 30 degrees here in Chicago. I landed on PintyPaint (comes from Spain) - I researched it and wanted to buy local, so I could work on this week while I'm off from work. Turns out JoAnn carries it so I scooped up 2 cans and started. At first, it seemed a bit strong, but I opened the windows a crack and had the fan on. It's dry enough in 30 minutes to do another layer. I got a nice soft white that is matte. 3 coats and it was perfect.
Hanging the Ray Storey chandeliers was a challenge, I had to ensure the length of chain was the same for both, and I scrounged my old jewelry and patiently attached them. Needed to drill a bit up in the peak to ensure I could feed the wire through to the exterior roof.
Gluing the Sue Cook corbels, the custom arches and the Unique Miniatures trim...all coming together. It's been a long time coming and I've invested lots of time (and money) into this room, and I'm happy it's done.
