Talk about DIY Inspiration! When I saw Lilly Jimenez, balloon artist on the show Making It, I couldn’t be more inspired. Her balloon creations are amazing! With my 3-year old’s birthday coming up, I just had to try to make my DIY Seashell Balloon Art piece.

Balloon Seashell Instructions


I think the best way to learn how to do this, is to watch the video I made. It’s difficult to reiterate exactly how I made the shape. I was truly winging it, but glad I recorded making it.

  1. Measure and cut the poster board in 4” wide strips, lengthwise. I think I used 10 or 12 strips.
  2. Use the strips to create a shell outline. I started in the center of the shell and worked my way out. Tape it together as you go.
  3. Once your shell is formed, tape down and flaps.
  4. Blow up balloons to fit inside each compartment. Start with the larger ones first and tape them to the sides of each compartment.
  5. Begin filling in the blank spots with smaller balloons. Play around with size and color.
  6. Lastly, Set the shell upright and fill in any other missing pieces. Add a white balloon for a pearl if desired.
