If you don't know too much about the person, but you know their birth date then you can still make a collage all about them! Consider birthday card ideas using their zodiac sign, precious stone for the month of their birthday, and if you know the year they were born you could also include their Chinese zodiac sign. If you still need some filler space, then find out some interesting facts related to their zodiac sign and print or write them on the front of the card. Everybody loves to read what they're all about and it could be a fun conversation piece so you can get to know the person better!
Lastly, funny birthday cards are no longer limited to being found in stores or shopping centers. With the help of personal computers, anyone can design their own humor greeting cards at home without needing to print them out on special paper. In fact, not only can personal photos and videos be shared through these digital gifts, but the cards can also be emailed instantly to anyone with an Internet connection and email address.
