Just pull the sides and the card opens to reveal the inside and the backside of the front panel. Lori has created these great card files in many different panel shapes. Everything from scalloped circles to squares to stars.
Here is another look at the card from a different angle. I used papers and pretty stickers from the brand new collection Sweet Girl by Lori Whitlock for Echo Park. The sentiment Happy Birthday came from another card file by Lori called, Happy Birthday card set.
I also made a fun flip card for a boy using the brand new paper collection, All About A Boy, by Lori Whitlock for Echo Park. This particular flip card file also includes the panel shapes that I used to cut the patterned paper from.
Sorry that the card looks a little warped. These kinds of cards are little hard to keep standing for photographs. This photograph shows what the inside of the boy card looks like when pulled apart.
