Cute Mermaid Birthday Party Ideas, Printables, Scrapbook Supplies by Amy Locurto

My baby girl wanted a Mermaid Birthday Party.

Here is what she got…. I hope you enjoy these fun ideas from my daughter’s Mermaid Party!

**Exciting Update!** My mermaid designs were turned into super cute party and scrapbook products! You can buy them here.

I had the best time drawing her as a mermaid for the invitation!

Her name was on the invite, I just put “girl” on here for the blog. I designed this invite especially for my daughter (this design is not for sale), but I do have a really cute version of it which is available in my shop. You can customize it with your own party details before printing too!

Mermaid Party Table & Food Ideas

I didn’t go crazy on the decorations as I wanted something simple and easy because I put all of my time into the food and crafts. The backdrop was sheer sparkly fabric and a few balloons. I wanted a feeling of being under the water.

I think these cupcake toppers took a lot longer to design than to make the sandy beach cupcakes! I now have the Mermaid designs for sale in my shop.

The food was sushi sandwiches, brownie bombs, brownie starfish pops, goldfish crackers, fruit, pizza and blue Gatorade.

Little Mermaids

The guests were three little girls, their siblings and one little boy (her boyfriend!).

I made these easy no sew mermaid tails for the girls. I didn’t realize how tall they all were compared to my girl! So some were way shorter than they should have been. You can see directions on how to make these at the bottom of this post. Of course, each mermaid got a crown too!

We had lots of fun and games!

Pin the crown on Ariel (which even the older brothers wanted to do), an under the sea treasure hunt and the older siblings had a blast in the dance contest! Oh my… there were some moves going on that should have been outlawed!! LOL! And of course opening presents at the end was a big highlight!

Taking photos as a mermaid was a hit, even with a few boys!!

I bought a large blue foam core board and spray glued a large cut-out of my mermaid drawing. I cropped in close so you couldn’t see their hands holding the board.

Mermaid Decor & Goodies

I found cute Ariel lunch boxes half-off at the Disney Store and filled them up for goodie bags. The boys all got Sponge Bob cups filled with pirate goodies.

Centerpieces were big cut-outs on silver chargers with pearls and shells surrounding them. I also had a table with a treasure chest and more food, but didn’t get photos.

DIY Ideas for a Mermaid Party

How to make a no sew mermaid tail.

Party Craft Idea- No Sew Mermaid Tail - Living Locurto

I am not a sewer, so I didn’t do any particular measuring. The best advice I can give on how to make these yourself is to measure your little mermaid’s waist then add some extra fabric for wrapping. Also measure from her waist to the floor for the length.

For more instructions on how to make the mermaid tails, visit this updated post about it here.


Sushi Sandwiches

Roll cheddar cheese, cucumbers, cream cheese and turkey up in a piece of white bread. I also added mustard to some.

    Do you have the dimensions for the mermaid tail?
    How wide and how long for a 3 year old?
    Do you need the seam down the middle of the back or could it all be one piece of fabric?

  3. […] For her 6th birthday, my daughter wanted a mermaid party because of her love of “Barbie in a Mermaid Tale”.  She made it clear she did not want an Ariel party, and I was unable to find any decor for the Barbie mermaid movie, so we decided to have a generic mermaid theme instead.  I figured it would leave a lot of room for me to get creative.  :-) I got most of my inspiration from Pinterest and Peaceable Kingdom’s Mermaid Island board game.  I envisioned a lot of aquamarine and coral colors.  I carefully chose fabrics to use as backdrops and to drape on tables.  I also made a lot of the decor myself. For the cupcakes, I cut cupcake wrappers out of cardstock and glued pearls on the wrappers.  I also made the cupcakes and icing from scratch because I wanted to use natural ingredients.  The light pink color of the icing came from strawberries.  I used the playing pieces from the Mermaid Island board game and copied them onto cardstock to make toppers for the cupcakes.  They turned out exactly as I’d envisioned.  I also made the birthday banner out of cardstock and carefully cut out sea creatures to decorate them.  It also turned out as I’d hoped.   In the living room, I draped different shades of blue crepe paper down the fireplace to look like water and I attached fish, seahorses, and seashells to it to look like an underwater scene. My mom told a mermaid story about treasure and then we proceeded outside to a treasure chest pinata to find our loot!  We also played “pin the crown on the mermaid”. One of the most special and time-consuming things I made was my daughter’s mermaid tail.  It took a lot of time and planning to get a basic pattern, but I had fun with it and my daughter felt really special. :-) We had a wonderful time and I think my daughter really enjoyed her party.
