How to Make a Stunning Coral Reef Decoration for an Under the Sea Party

Decorating for Vacation Bible School is always a daunting task and this years theme, Ocean Commotion had us all scrambling for ideas and exercising our Pinterest muscles.

I ended up combining several techniques on 2 coral reefs and they became the spotlight of our craft room. This coral reef would be a colorful and beautiful addition to any under the sea or mermaid party decorations.

Keep on reading for all the tutorials to make you a coral reef pro. You can use all or just some of the techniques outlined below.

Here’s what I used:

  • Boxes
  • Brown craft paper
  • Pool Noodles
  • Floral Mesh in several colors (Available at any craft store or fake floral department of big retailers)
  • Tissue Paper in several colors
  • Packaging Peanuts
  • Spray Foam (“Great Stuff” from the hardware store)
  • Spray paint
  • Fishing line
  • Wire
  • Wooden BBQ sticks
  • Toothpicks



Make the Coral Reef Base

First arrange the boxes in a reef like fashion.

Crumble the brown craft paper and drape it on the boxes.

I know. Looks suspiciously like a couple boxes covered with brown paper. We will make magic with that.


Make Tube Coral

Cut the floral mesh into 1 foot strips, roll them, fold them in half, and attach 3 to 4 pieces together with some fishing line. Then attach a wire hook.


Make Paper Sea Anemones

You’re basically making a tissue paper flower with very pointy petals. Here’s how I did it:

Stack 4 square paper tissue sheets of the same color.

Fold accordion style in about 1″ folds.

Wrap wire around the middle.

Cut the ends very pointy.

Carefully separate the sheets of tissue paper on both sides.

 

Wrap the wire around the bottom to bunch the sea anemone to one side. You’ll use the wire to stick the anemone into the cardboard box.


Make Pool Noodle Coral

Cut a pool noodle in half and another in 2 uneven pieces. Cut in a big swirl pattern around the noodle, starting at the top and stopping about 6 inches to 1 foot from the bottom. Cut inside the swirl at least one or two more times.


Make Coral with Spray Foam

I found this good tutorial on Pinterest so I’m re-posting here:

“Things you’ll need: Large cardboard/wood surface – lined with wax paper Wood dowels Can of spray foam Spray paint

What you do: Place wood dowel on wax paper and secure with tape. Spray the foam over the dowel in an organic free flowing motions to create something that resembles coral. Note: Foam will expand so don’t spray too much in one area. Let dry overnight. Carefully peel off wax paper. Then spray paint.”

This is one of mine:

I made a bigger one on this reef. You can see in the back. I also used a honeycomb lantern as brain coral on this one.


Make More Coral out of Packaging Peanuts

Just string white packaging peanuts on a wooden BBQ stick. Use toothpicks to make the arms. You can stick or glue a couple together and spray paint it if you wish. I left most of them white (like dead coral).

They look great in the back!


Put the Coral Reef all Together

Now you’re ready to use the wire ends to stick all these wonderful items in your cardboard boxes in an organic coral reef fashion. Stab BBQ sticks where you want the pool noodles to stand.

If things keep on falling you can use some of this fantastic product.

The burst of color on the coral reef will amaze your guests.

    Thank you for sharing some great ideas. How did you cut the pool noodles? Every time I cut mine, they fall off or you can not see the spiral.

  2. Chelsey says:

    Love all the ideas you shared. I am excited to try making the sea anemone you shared and I liked how you used BBQ sticks to hold the pool noodles in place. Your coral reef looks awesome!

    We love this creation! One question. How do you attach the pieces to the boxes? Does the wire just poke through the box? Thanks in advance!

  7. Kelly says:

    I love this. Thank you so much. I’m making a mermaid in coral lantern for a parade in Atlanta and you just completely covered everything for my coral base! It’s going to look awesome now!

  8. Teresa says:

    I actually I am being paid for making a coral reef decoration, I am sorry but I am copying this. It is so wonderful. By the way, what kind of fabric you used with the paper lantern to make the jellyfish? Thank you and congratulations, it is beautiful.

    • Press Print Party says:

      Hi Teresa, I’m so glad my design can help you. That’s what I’m here for. The jellyfish paper lanterns don’t have any fabric. It’s actually strips of plastic tablecloths that have been stretched. Hope that helps. I’d love to see your final product! Nathalie

    So do you cut around the outside with the swirl. I know I am asking too many questions but rather confused. So you use one cut and then cut two more from it, got that now. I just don’t understand how to get started. So when cutting do you turn the noodle to get the swirl?

    I love, love, love your coral reef display! I was wondering do you make any of these items and sell them. I would love to use this in my classroom next year as I am doing an ocean theme, Thanks Ashleigh
