Here is my Card in a Box before it is decorated and with the coordinating envelope.
You can see the strips of clear clamshell packing that I cut to to hold my flowers and balloons. I like to use the clear packaging so it looks like the embellishments are floating.
I used hot glue to hold the clear strips to the box and embellishments. I used The Card in a Box Embellishment set to create the flowers, balloons and Happy Birthday (I really love how easy this is to create with the embellishment kit).
I cut the grass from Zoo Balloo and the butterflies are Anna Griffin.
Here you can see the card all ready to go into the envelope and in the mail.
