Mermaid Party and Oyster Cookie Tutorial

We celebrated my eldest niece T’s 6th birthday this past weekend with a mermaid party. My mom, sister and I divided and conquered. We had so many fun decorations, delicious (and adorable) food, games and of course a mermaid outfit (more pics and tutorial to come). On the menu were shells and cheese, pigs in a blanket which for the day we called pigs in shells, fruit galore, veggies and hummus, sushi, vegan cupcakes, and an awesome mermaid cake which my mom made (yes that is fruit roll up wrapped around the barbie).

I spent WAY TOO LONG making cookie pops that doubled as decor. The weird ones were supposed be sand castles (they tasted yummy). And I also did some fun mermaids and seagulls which I thought turned out pretty cute.

One of my mom’s contributions were these super awesome and easy oyster cookies. We got the idea from Rook 17 who, by the way has so many amazing creations.

All you do is buy pre-made madeleines (we found ours at Costco) cut off a little of the cookie’s center (where the “pearl” will go) and then “glue” the pearl (we used candy coated chocolate balls) with royal icing to one shell and then with more royal icing glue on a top shell. After they dry completely run another bit of royal icing along the front edge of each shell and top with sprinkles. Easy and so cute.

My sister and I went crazy decorating. She did a fun streamer wall and I did “seaweed” from each of the lights. The nieces and I cut seahorses and starfish out on my Cricut and then we hung them all over. The girls were in charge of putting shells everywhere. So inexpensive and easy but it really made the house look festive.

My husband drew a mermaid for pin the tail on the mermaid and we had the kids each color in their tails and before dizzying them up. We also had a little felt squid making craft in which I totally lugged my sewing machine downstairs and sewed them while they waited (seriously so much easier and cleaner than trying to glue them!). We did presents (at one point T opened socks and yelled an exclamation of joy, haha what a goofy kid). And of course a lot of good old fashion hanging out.

It was a lot of work but I loved it. I think it was my favorite kiddo party we’ve had so far. And as a bonus the kids are all old enough that they don’t need full attention so we just let them go crazy in the play room. And they did go crazy it was like a screaming crazy wild zone in there. But it was so so much fun!

I’m pretty proud of T’s little mermaid outfit. I can’t wait to share more pics and a tutorial for that soon.
