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.
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.
