Something identical or Very similar.

I swear to god I had some at one point, and I thought they were base game. To my luck when I want to use them I can no longer find them.

I did have to reinstall the Sims a while back, and I didn't get all my cc back. So I don't know whether what I had was part of a house, or a package I downloaded.
But please please please someone tell me there is some of these that are not part of other expansions. (I have all I want.)

Thanks muchies in advance.

The French panels you are thinking of might be from the World Adventures EP (attached a screencap).

The-Regal-Sim has a lot of French-themed content on their blog:

EDIT: the ones above are more ornate. I looked a bit more through my stuff and found these: http://modthesims.info/download.php?t=468951
I think they are closer to what you're looking for

They are a lot closer to what I was looking for. Thank you!

I could always figure out how to make em if it comes down to it.

I'm not sure where found the orignal ones I had but I know I found them after I bought the Glitter and Glam Bedroom Set from the store. I was inspired to make a similar room, and then never did. I liked the cut corner over the squared ones.

I dunno if that link will help in my search, but I do know they where single panel, where the ones is that picture look to be dual/paired set.

Those panels are from Ambitions, they're categorised in Wall Sets. :)
