Introduction

This idea comes from our friend Kathleen Ballos. While there may not be a pot of gold at the end of this rainbow, we're sure you'll love it just the same.

materials

  • Balloons in rainbow colors
  • Balloon pump
  • Cardboard
  • Craft knife
  • Pencil
  • String
  • Packing tape
  • Electrical tape

steps

  1. Draw an arch (almost like an upside-down J) onto cardboard and cut out (our version is approximately 14" wide and 5' tall.) Depending on the size of your cardboard box, you may have to cut the cardboard into pieces about 14" wide and use packing tape to form an arch shape. Add a piece of cardboard to the bottom slightly wider than the arch (this will be the cloud).

  2. Start adding the base layer of balloons. To do this, blow up the balloons with the pump, tie, and tape to the edge using electrical tape. Line the entire edge with red balloons, varied in size for scale.

  3. Fill the remaining cardboard with the remainder of balloons to complete the base layer.

  4. To cover any gaps in the base layer and add depth, inflate small-sized balloons. Use electrical tape to stick them in place.

  5. Add white balloons onto the bottom to form the cloud in the same way.

  6. To hang, use packing tape to attach a loop of string to the back of the rainbow and hang from hooks/nails on the wall.
