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.
"It's just a Number!" Collage _ If you know how old your birthday gal or guy is turning, then take it to the next level! Start cutting out their birthday number from magazines, newspapers, bus schedules, junk mail flyers, and start collecting! If you can't find a lot of numbers, start spelling out the number, for instance, s_i_x_t_e_e_n, from letters found in different media. The spelling of the birthday age will help to fill out the card collage. The letters for spelling out the age do not have to be the same font or color __ think of those infamous ransom notes and create your collage with that effect in mind.
