For example, humor birthday cards with pop_up pages are not only visually impressive, but they are also fun for children or anyone who enjoys interacting with pictures and movable parts. Even the dourest of individuals can be amused by the card's level of detail well after it is first opened by the recipient. These cards are ones that will be treasured for years to come even after that year's birthday.
Crafting Tip: When brainstorming birthday card ideas using the collage technique with different media you may run into the problem of "filling out" the entire collage. To alleviate this issue, consider using patterned paper as the background of the collage to fill in any blank spaces ahead of time. Or use a repetitive signature piece of art of fill in the blanks, such as stars, colored buttons, hearts, happy faces, and other embellishments.
