Things You'll Need:
-
Step 1
Use a blank greeting card or a piece of card stock paper that has been cut to the desired size and folded in half.
-
Step 2
Draw or trace a rainbow shape onto a piece of heavy white paper - card stock or heavier is best. The rainbow should be 1/2 to 3/4 the length of your greeting card and 3/4 the width of the open greeting card.
-
Step 3
Use a compass to make the arcs of your rainbow. Outline the rainbow shape with a black felt-tip pen or permanent marker. Color in the sections of the rainbow with crayons, markers or acrylic paints.
-
Step 4
Use a ruler and a pencil to add 1-inch extensions to the ends of your rainbow.
-
Step 5
Use scissors to cut out the rainbow shape along the outside of the black outline marks and along the penciled-in extensions.
-
Step 6
Fold the rainbow in half vertically, blank sides together. Make a sharp crease.
-
Step 7
Fold each extension up against the decorated side of the rainbow shape. Make a sharp crease at the point where the decorated end of the rainbow meets the undecorated extension.
-
Step 8
Position the rainbow over the open greeting card so that the rainbow's center fold lines up with the center of the card. The extensions should be positioned to the front of the rainbow and lying flat against the greeting card.
-
Step 9
Make sure the rainbow is positioned correctly, and glue the extensions down to the surface of the greeting card.
-
Step 10
Allow the glue to dry thoroughly, and decorate the remainder of the greeting card as desired.
