Ribbon lined Alligator hair clips (Suckers will work also)
Use a box knife to make parallel cuts of equal length on your card. They can be horizontal or vertical. Now just squeeze the clip open and weave it through the slit. Punch a hole in the upper corner and tie it to a balloon. It is the perfect fun little party favor or invitation.
Need a little help lining alligator clips? http://www.girlythingsbows.com/ is one of my favorite sites for very simple and basic instructions. The instructions listed across the top of the site are in alphabetical order. Once you have a lined clip you can glue on anything from crystals to buttons. My favorite are satin roses. Or you can slide in suckers in the slit instead and just tie ribbon to the stick.
I had the card featured in my example custom printed by Vista Print, http://www.vistaprint.com/. They are always having free offers. I only had to pay shipping. I recieved over 100 small postcards. I also use Vista Print to custom print thank you cards, care instructions, personalized invitations and business cards.
