Redecorating speaks more for money
If you cannot afford to decorate or redesign your room, it is worth mentioning that even simple re-decoration of walls will be of great impact at the end of the day. The things you do might be simple, nut the impact that it delivers is something to experience. To accomplish this, you need to first decide on the theme, your wall should convey.
Long cherished memories of your childhood can be reflected on your wall to convey that gone passed were days of joy. Favorite childhood photographs can be collected and can be made into a black and white frame, and can be hoisted on the wall.
If you have a favorite musical instrument, or a favorite sport equipment of the past, hang it on the wall. Your favorite movies of the past can be recollected and hanging one or two of them on the wall, framed with brown wooden material would look simply brilliant.
