It is good to start by making a rough map of the wall and positioning of pictures on the paper to decide beforehand where to hang which picture. Once decided, you can begin hanging your pictures according to your drawing.

Use small sturdy nails and use studs for placing nails on walls to avoid any damage to the wall, especially when you are renting the apartment or living in a dormitory, which may result in deductions from your deposit.

Studs and stud indicators can be found at local hardware stores and help in centering pictures and hanging them properly. Ensure that the wire from which are going to hang your picture or decoration on the wall is strong enough to bear its weight and won't come loose while you are hanging it.
