My client was great for this job, in that she was very open to the ideas I had and was very trusting in letting me execute them. I am a huge Alphonse Mucha fan (the similarity to his styling is apparent) and had wanted to do something like this for some time. She is very happy with the final results.
The Nouveau design was kept in the same color scheme that already existed in the room. The sage green color was added into the background of the decoration to draw out the sage green within the tiles and emerald green jewels to also match the tile work. First the wall paper was stripped, then I'd done a textural surface treatment with a ragging off technique in tans and a light gray to create an aged feel. It isn't shown in these photos but the vanity cabinets were done in a similair way and incorporated the diamond shape on the light fixtures with a trompe l'oeil engraving on the drawers.
