I did this Happy Birthday Photo card in shades of blue. You can choose any color you want. The base card needs to be two sided because you do see a little of both sides, but not much. Patterns would work well with any part of this card as long as the pen showed up. Just don’t use too many patterns. This would get confusing.
Assembling the Happy Birthday Photo Card
First re-crease the fold. Attach the inside of the frame first. Use thin foam tape down each side for this. That gives the space to slip several pictures in. To do this, first lay a picture on the back of the base card over the hole. Then place the foam tape on three of the edges making sure not to touch the picture. Leave the side open. That way you can add pictures and they can remove them later. Then remove the picture and stick the blank dark blue piece with writing behind the hole without the writing inside the card. This holds the pictures in the frame.
Then, assemble the balloons and attach them to the front of the card. Next, glue the presents to the dark blue rectangle with the writing. Then assemble the cake and attach it to the dark blue piece behind the picture Lastly insert the picture(s) into the card.
And your Happy Birthday Photo Card is done. It fits in an A7 envelope for mailing.
