As far as interior decoration is concerned, there are few rules, because it varies according to the tastes of each. Still, there are choices that designers put aside because they harm the environment of spaces.

ANDthere are few strict rules regarding the decoration of the house, since it varies according to the taste of each.
Still, there are things that will always be rejected by interior designers, as mentioned in an article on Martha Stewart's website. We've highlighted five. Make a note.
1. Furniture to be combined
Interior designers dispense furniture sets to match. This makes the house lose its personality and looks like a window.
“ The houses are more interesting when they reflect different layers of personality”, notes Lonni Paul, director of Lonni Paul Design.
It recommends creating carefully selected spaces with multiple layers. Furniture should complement, but not belong to the same set.
2. Fake finishes
If you have a budget for it, you can choose marble or wood. The finishes that mimic these materials may be cheaper, but they do not have the same personality.
“I value authenticity in design,” notes Paul. Invest in something that resists time, both in durability and style.
3. Theme decoration
Everyone wants their home to be fashionable or in tune with a theme, but it's worth not exaggerating.
“ In my home I prefer a scale and collection approach, which can evolve as my tastes change,” said designer Sarah Beecham.
You should therefore invest in natural materials with details that will highlight your space.
4. Large and colorful couches
The sofa is the central point of your living room and therefore it is important to hit design. Some opt for a large and colorful model, which ends up mastering almost the whole environment.
Asprea claims that after some time the couch may seem old-fashioned. When choosing a sofa choose first by a neutral color or even a sage green or slate blue.
5. Geometric wallpaper
Some design choices are frequent in corporate spaces, making your home uncomfortable. Geometric wallpaper is an example. “It has a structural aspect — the patterns are quite rigid and of great contrast, and tend to be more suitable for commercial environments or with strong visual identity of the brand,” notes Karen Asprea, director of Asprea Studio.
