One of the best birthday card ideas is to get a big card that has a picturesque front. You can sign in the wishes and your name at its back. Most of the times, people decorate it in their living room or bedroom as a wall hanging. It stays on with them for months & years ahead. This especially works with the teenagers and kids. They love to place their favorite cartoon and fantasy characters in various places in the house.
Another tip is to try talking cards. The moment you open it, it would say 'Happy Birthday' or some sweet little words. Some times you would come across interesting things like a cat meowing or a dog barking. They are also real fun. These players are battery operated so it is another item to keep in the list. Likewise other interesting idea is to take a musical card. You can choose among the birthday tune and some happy kids' songs. At times, you may also gift a card that plays classic songs.
