Try decorator supply. They've got a PDF catalog that's got gobs of these types of panels, mouldings and ornaments. It's not cheap but it's every bit as comparable to this stuff in this video.
Alleh freaking luja! Someone actually gets it! I look for baroque and its some french provincial or queen anne furniture and plain walls, or plain walls period!

Its like when i say baroque, nobody gets it-and thier in interior stuff which is the worst part.
