The Tuscan look is already on it’s way out. In a few years it will be very dated. If you have the look now, enjoy it while you can. If you want to update it, or if you want a more classic Tuscan look, here is what I would do:
1. Instead of a yellow color wash, just paint the walls a sunny yellow or terra cotta color, don’t mess with a faux finish.
2. Accessories. Take at least 3 things out of your room. Don’t keep anything that you don’t love. Don’t hold onto anything because it matches something that you really love. Cut the beads & fringe off of most of the stuff, only leave it on one or two items to make things sparkly. Leave the rusty scroll things on the wall if you love them. Just remember to take them off when you don’t love them anymore.
3. These rooms usually have leather sofas (great) or ultrasuede, these are fine as is.
4. I love, love LOVE Spanish tile. Fake terra cotta tile, not so much. If you have one of these floors that you don’t love, love LOVE, bring in a neutral rug. The more neutral colors you can bring into this space, the better.
5. Take out the Tuscan prints if you are tired of looking at them. Instead, think of what you love about the Tuscan look, is it the colors? The architecture? Then find a print with those things. This will be a much less literal translation.
This will transition your room into the next millennium while still leaving the warmth.
