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.
Humor birthday cards with unusually large shapes and sizes are also very effective ways to heighten a birthday party celebration. Just as how they can hold an enormous amount of content, the cards can also command an equally enormous amount of attention and detail. More importantly, the card's excess space and size will come in handy for hiding special knickknacks and novelty gags or a gift card without being too bulging or tearing the envelope.
