Pro tip: Use a piping tip for this design to ensure the lines are consistent. This tutorial uses Wilton 12 but Wilton 8 is a good alternative. If piping tips aren't available, ensure the piping bags are cut similarly.

Bake and cool cookies before decorating. Make sure cookies are fully cooled. If they are warm, the icing will run off of them. Make royal icing. Learn how to mix different consistencies of royal icing here>>
Prepare the following icing colors:
Piping Consistency:White
Red
Orange
Green
Blue
Purple
Pink -
2Pipe an arching red line at the top of the rainbow shape, in between the clouds. Wait for the icing to dry 20-30 minutes. This will ensure that the icing does not bleed into the next color.

Pipe the orange, then green, then blue, then purple, and pink in the same manner that you did the red line.

Make sure that you let the icing dry completely between each step to avoid color bleed.

Color bleed is when a darker color royal icing begins “bleeding” into an adjacent lighter color of royal icing. By letting the icing dry between steps, you can reduce the chances of the colors bleeding into each other.

Pipe the lines close together so that there are no gaps between the colors.

7Now that your rainbow is done, it's time to move onto the clouds. Using white piping consistency icing, pipe circles on either end of the rainbow. Make sure that the circles you pipe are not touching to start with. This will ensure that there is definition in the pipework. Wait for the circles of white icing to dry for 20-30 minutes before piping your next batch of circles.

To create puffy clouds, begin overlapping the white circles as you pipe them. Be sure not to pipe onto wet icing, as you will lose the definition and fluffiness in the clouds. Repeat this process until the entire surface of the cookie is covered.
