Easy Pop Up Rainbow Card

Learn how to make a pop up rainbow card! This 3d Paper Rainbow Card is super duper easy to make. I love that it is made from white paper, though if you wish you can layer strips of colored paper and build a rainbow that way! 

Time needed: 15 minutes.
Depending on how you make your basic paper rainbow, this timing of this card making craft will be shorter or longer. E.g. if you use watercolors, making your rainbow is quick and easy, but you have to allow for drying times. If you use pens, there is no need for drying, but it will take longer to draw.. or you can use strips of colored paper stuck together. But making this card doesn’t take very long at all if you are in a hurry. But do take your time over it!

To make a 3d Paper Rainbow Card, you will need:

• Card stock (we used A6 folded in half)
• Paper (we used the length of an A4 sheet of paper  so approximately 30cm), as well as scraps for the clouds
• Pens, watercolors, or paints
• Scissors
• Glue Stick

Measure your rainbow width
It is important to mark your paper to have the right fit for the card. The rainbow you paint must not be longer than width of the card (when opened).

Create your paper rainbow
As mentioned, you can use pens, watercolors or strips of paper stuck together to create your rainbow. We used water colors and let them dry.

Cut your out your rainbow
Once fully dry, cut off any whit excesses, so you are only left with the drawn or painter paper rainbow for your card.

Fold your accordion rainbow
Now is time to fold the paper into an accordion and making a folded accordion. Fold the short edge of your rainbow approximately 1cm. Then flip over and fold in the other direction. Keep going until you have a full concertina rainbow!


Add glue to one edge of the rainbow
Add glue to one edge of the rainbow and secure in the card – going across the width and perpendicular to the central fold. Leave space for writing and kawaii clouds.

Now add glue to the top of the remaining rainbow
Add glue to the top of the accordion rainbow and fold the card shut. Press gently but firmly. When you open up the rainbow will be secured. Let dry fully before opening and shutting too much!

Add further decorations
Start cutting further decorations – e.g. paper clouds.
