Step 1. First, cut the 2 pieces of paper to make the card.
Step 2. I like to cut the outside paper (blue) to 8.5 x 6 and the inside paper (white) to 8 x 5.5. This will allow the card to fit into a 6X4 envelope for mailing it.
Step 3. Then take the inside color and fold the single sheet of paper in half lengthwise. On the middle crease just created, draw 4 lines measuring 4 cm, 3 cm, 2 cm and 1 cm. I made each of these lines approximately 2 cm apart and they are 3 cm from the top and the bottom of the second piece of paper.
Step 4. Then gently cut on the lines on the folded side of the paper until you have parallel cuts. Try to cut in straight lines.
Step 5. Fold lines on both sides to create the creases.
Step 6. Then open up the middle insert and push these rectangles forward and fold them down gently to create the birthday cake on the side of the card. Each single slit will pop out from the extra cuts.
Step 7. Decorate the birthday cake with the markers and the stickers. You can draw balloons with crayons for a birthday. This is a great time to write a happy birthday message as well.
Step 8. Next, fold the outside color paper in half lengthwise. Finally glue the middle insert onto the outside color (blue sides) with the glue. The end result will brighten someone's day.
