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.
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.
