Free mermaid crochet pattern - Easy amigurumi tutorial for beginners

July 3rd, 2025

Have you ever dreamed of making a cute crochet mermaid? For years, I had this image in my head of a sweet, handcrafted mermaid, but I never quite got around to it. Well, this year, I finally made that dream a reality!

I designed my very own amigurumi mermaid, and I loved her so much that I wanted to share the experience. I hosted a Crochet-Along (CAL), and the response was absolutely incredible! More than 200 amazing crafters joined in to bring this little mermaid to life. Seeing all the different color combinations and happy faces was the highlight of my year.

The CAL was such a success, and the community we built was so inspiring, that I knew I had to share this pattern with everyone. So, I’m thrilled to release my free crochet mermaid pattern for you today!

Is This a Beginner Crochet Pattern?

This is the perfect project for an adventurous beginner! If you have a little bit of amigurumi experience, meaning you’re comfortable with the basics like a magic ring, single crochet, increases, and decreases, you can absolutely make this mermaid.

I designed this pattern to be as clear and straightforward as possible. However, if you get stuck on any part, please don’t hesitate to reach out! My goal is to help you successfully create a handmade toy you can be proud of.

The Perfect Quick Gift & Summer Crochet Project

Are you looking for a quick crochet gift idea for a little girl’s birthday? Or maybe a special present for a baby shower? This mermaid is your answer! She works up relatively fast and her charming design is guaranteed to make someone smile.

This is also a fantastic summer crochet project. You can work on it by the pool, at the beach, or on a lazy afternoon in the backyard.
