What You’ll Need

  • 16 pink balloons
  • 16 orange balloons
  • 16 yellow balloons
  • 16 green balloons
  • 16 blue balloons
  • 16 purple balloons
  • 4 helium tanks
  • 6 balloon weights
  • Purple curling ribbon
  • Scissors


Step 1: Inflate Balloons

Begin by inflating your first balloon. For a 12-foot arch, you’ll need 96 balloons that will be inflated and tied together to form clusters of four balloons each. You can buy your own tanks, or have your balloons filled at your local party store.

Step 2: Tie 2 Balloons Together

Inflate a second balloon and tie it onto the first to make a pair.

Step 3: Tie Pairs Together

Repeat Steps 1 & 2 to make a second pair of balloons. Now join the two pairs of balloons in the center – twisting their centers around each other – to form a cluster of four balloons. Make sure the balloons in each layer are uniform in size so all the sections of the arch will look even.

Step 4: Tie It to a Balloon Weight

Cut a long strand of ribbon (approximately 48in) and tie one end to a balloon weight. Tie the other end around the center of the balloon cluster you just made. You’ll be adding three more clusters underneath this top layer so make sure to leave enough room underneath.
