This is a really simple card. I used a solid, print, 2 brads, another small strip of a solid and whatever you want for the words. You could stamp them or in this case I ran it off on my computer.
Whatever color you pick for the inside is what you see on the front bottom of the card. I folded the card in half and on the front flap I cut a smiley face by trimming off the edges of the card. I glued the the print on the front and cut it to match.
Next, using the brads, I attached the Happy Birthday paper onto the coordinating solid and then glued on the solid to the card. That's it. You can change it up and use whatever words you want.
