Designing something is extremely hard for those people who lacks imagination. More over designing a room is quite something different,because you won't
be designing something new for to wear but to live inside. In this case you should be choosing your favorite belongings to use inside of your room, but be aware of the necessity of certain harmony among the goods that you have planning to use inside.
Even though colour is important for harmony room can contain different colours but in the same theme of design. Those goods must reflect your personality and your soul most of the time. You must feel better when you look at them.That's why those belongings in your room are important, they are more important than room temperature if you ask me.
1) Use familiar objects to your childhood, that will help you remember good times of your life,
2) Use Suitable objects, you do not want a messy image on your side, messy rooms make your mind messier!
3) Feel The harmony, Colours can be different but designs needs to be close at least.
4) Some Times Less is More, Be practical and use the things you need the most!
Peshtemal on the other hand; out of subject on this blog! But of course you can use it in your room, on the wall, on the floor, as a throw, as a runner for bed, anyhow you want!
See ya !
