Among her most beloved creations is Kailani the Mermaid — a pattern that has captured the hearts of crocheters around the world and become a staple project for anyone who loves fantasy-inspired fiber art.

In this post, we’re diving deep into everything you need to know about the Kailani the Mermaid crochet pattern. Whether you’re considering picking it up for the first time, looking for tips on how to make the most of your finished doll, or simply trying to decide if this is the right project for your skill level, you’ll find everything here to help you get started with confidence.

Who Is Rachel Borello Carroll?

Before we get into the pattern itself, it’s worth taking a moment to appreciate the designer behind it. Rachel Borello Carroll is a crochet pattern designer based in the United States who specializes in soft dolls, amigurumi, and character-based creations. Her patterns are widely admired for their clean construction, expressive faces, and the sense of story that each finished piece carries.

Rachel’s design philosophy centers on creating dolls that feel personal and handcrafted in the truest sense — each one looks like it could belong in a storybook or on a child’s most treasured shelf. Her Etsy shop and website have attracted thousands of customers and fans, and her patterns have been made up by crafters on every continent.

Kailani the Mermaid is a perfect example of everything that makes Rachel’s work so special. The name “Kailani” is of Hawaiian origin and means “sea and sky” — a fitting name for a mermaid doll that evokes the colors and magic of the ocean.

What Is the Kailani the Mermaid Crochet Pattern?

Kailani the Mermaid is a crochet doll pattern that produces a soft, poseable mermaid figure with a beautifully constructed tail, flowing hair, and delicate facial features. The finished doll is designed to be cuddly and display-worthy at the same time, making her equally appealing as a child’s toy or as a decorative piece for a nursery, bookshelf, or creative studio.

The pattern walks you through constructing the doll piece by piece, including her body, tail, fins, arms, and hair. Rachel’s instructions are known for being clear and accessible, with detailed stitch counts and helpful guidance throughout. The finished Kailani typically stands around 12 to 14 inches tall depending on your yarn weight and tension, making her a satisfying project with a finished size that feels substantial and gift-worthy.

One of the things that makes this pattern stand out among other mermaid crochet patterns is the attention to detail in the tail construction. Rather than a simple tube, Kailani’s tail has shape and movement to it — a graceful fluke at the base, scale-like texture options depending on how you choose to customize her, and a color transition that allows crafters to get truly creative with their yarn choices.

Skill Level and Requirements

The Kailani the Mermaid pattern is generally considered an intermediate crochet project. If you’re comfortable with the basics — single crochet, increases, decreases, working in the round, and seaming pieces together — you’ll likely find this pattern very manageable. Beginners who are eager to level up their skills might also find it achievable with patience and a willingness to take things slowly.

You’ll want to be familiar with a few specific techniques before diving in. Magic rings (also called magic circles) are used frequently in amigurumi-style construction, so if you haven’t tried one before, it’s worth practicing ahead of time. You’ll also be working with safety eyes, which are inserted before the face is fully closed, so timing matters. If you’ve made a stuffed animal or an amigurumi project before, you already have most of the foundational skills this pattern calls for.

Rachel’s patterns are written in US crochet terminology, so if you’re accustomed to UK terms, you’ll want to keep a conversion chart handy to make sure you’re working the correct stitches.

Recommended Yarn and Materials

One of the most enjoyable parts of starting a new doll project is choosing your materials, and Kailani offers plenty of room for creativity here. Rachel typically recommends a DK weight or worsted weight yarn for the main body of the doll, though many crafters have successfully made her in different weights to achieve different sizes.

For Kailani’s tail, the color choice is everything. Some of the most stunning versions of this doll have been made with gradient or ombre yarns that create a natural color transition from hip to fluke without any extra effort. Teal, seafoam, deep ocean blue, coral, and iridescent purple are all popular choices. Metallic or shimmery yarns can also add a magical quality to the tail, though they can be slightly more difficult to work with if you’re not used to them.

For the skin tone of the doll’s body, Rachel offers inclusive options and encourages crafters to choose a shade that reflects their own preference or the child they’re making Kailani for. This is one of the reasons her patterns have such broad appeal — they’re designed with the understanding that mermaids can look like anyone.

Hair yarn is another fun element of this project. Many crafters use a different texture or weight of yarn for Kailani’s hair to give it a flowing, realistic quality. Bulky yarn, roving, or even a yarn with a bit of sheen can work beautifully here. The length and styling of the hair is largely up to you, and this is one area where individual crafters tend to make Kailani their own.

In terms of tools and notions, you’ll need a crochet hook appropriate for your chosen yarn (typically a 3.5mm to 5mm hook for common weights), polyester fiberfill for stuffing, safety eyes in your preferred size (12mm to 16mm are common), yarn needles for seaming, and scissors. Some crafters also like to use stitch markers to track their rounds, which is especially helpful when working on the body shaping.

Construction Breakdown: How Kailani Comes Together

One of the most satisfying aspects of working through any well-designed doll pattern is watching all the individual pieces transform into a finished character. Here’s a general overview of how Kailani the Mermaid is constructed, so you have a sense of the journey from cast-on to finished doll.

The head and upper body are typically worked first, starting from the top of the head and working downward in continuous rounds. This construction method keeps seams minimal and gives the finished piece a smooth, clean appearance. The facial features — safety eyes, embroidered details, blush if desired — are added during this phase, before the head is fully stuffed and closed.

The tail is worked separately and is arguably the most distinctive part of the pattern. It begins at the waist area and tapers beautifully down to the fluke, which is shaped with increases and decreases that give it that characteristic mermaid silhouette. If you want to add a scale texture, this is typically done with surface crochet or by working into the back loops only during specific rounds — a detail that can elevate the finished look considerably.

The arms are small but expressive, worked in the round with minimal shaping. They attach at the shoulder area and can be positioned however you like once seamed in place.

Hair is attached after the doll is otherwise complete. Rachel’s instructions typically guide you through creating hair loops or yarn lengths that are then attached to the head in a specific pattern to create the impression of a full, flowing mane. This step takes time and patience but is enormously satisfying when done.

Tips for Making Kailani Your Own

One of the greatest joys of crochet is the ability to personalize a pattern, and Kailani is a project that invites creativity at every stage. Here are some ideas from crafters who have made this doll and fallen in love with the process.

Experimenting with tail colors is probably the most popular way to customize Kailani. Consider using a self-striping yarn that handles the color changes for you automatically, or deliberately choose two or three complementary shades to create a hand-crafted gradient effect by switching yarns every few rounds. Deep ocean tones tend to photograph beautifully, but don’t overlook warm colors like rose gold or sunset coral for a more unconventional look.

Adding embellishments is another way to make your Kailani unique. Some crafters add tiny crocheted starfish or shells to the hair or around the waist seam for a whimsical ocean-themed touch. Others add a bit of sparkle with seed beads woven into the hair or small sequins attached to the tail. These details aren’t part of the original pattern but are easy additions that make the finished doll feel truly one-of-a-kind.

If you’re making Kailani as a gift for a child, consider what colors that child loves most and build the palette around those preferences. A little girl who loves pink might adore a Kailani with a magenta tail and golden hair, while a child who’s obsessed with the ocean might prefer something in true marine blues and greens. This level of thoughtfulness is part of what makes handmade gifts so meaningful.

Common Questions from New Kailani Makers

Experienced crocheters and newcomers alike tend to have questions when they’re approaching a new doll pattern for the first time. Here are some of the most frequently asked questions from people who have worked on Kailani the Mermaid.

How long does the pattern take to complete? This varies widely depending on your experience level and the time you’re able to dedicate to the project, but most intermediate crocheters report finishing Kailani in somewhere between 8 and 20 hours of working time. Breaking the project into sessions — one day for the head and body, another for the tail, another for assembly and hair — can make it feel more manageable.

Can the pattern be resized? Yes, with some experimentation. Using a lighter yarn weight and a smaller hook will produce a smaller doll, while a heavier weight and larger hook will yield a bigger one. Keep in mind that resizing a doll pattern sometimes requires adjustments to stitch counts in order to maintain the correct proportions, so this is best attempted once you’re familiar with how the original pattern is constructed.

Is Kailani safe for young children? As with any doll made using safety eyes, Kailani is best suited for children old enough that small parts aren’t a concern, generally ages three and up. For babies or very young toddlers, you may want to embroider the eyes instead of using safety eyes as a precaution.

Where can I purchase the pattern? The Kailani the Mermaid pattern is available through Rachel Borello Carroll’s Etsy shop and, depending on availability, through Ravelry and her personal website. It is a paid digital download, which you receive instantly after purchase and can print or reference digitally as you work.

Why Kailani Makes the Perfect Handmade Gift

Handmade gifts carry a weight that store-bought items simply cannot match. When you give someone a Kailani the Mermaid doll that you’ve made yourself, you’re giving them hours of your time, your attention, and your creative energy all wrapped up in something beautiful and lasting.

Kailani is particularly well-suited as a gift for children who love the ocean, fairy tales, or fantasy-themed play. She’s also a popular choice for nursery décor, especially for ocean-themed rooms where her colors and whimsy fit perfectly. Many crafters have also made Kailani as collector’s pieces or display items for themselves — she looks stunning in a bookcase, on a bedroom vanity, or nestled among other handmade items in a creative space.

For baby showers, birthdays, or holiday gifts, a handmade Kailani doll is the kind of present that people genuinely remember. The uniqueness of a hand-crocheted doll — with color choices made specifically for the recipient — communicates care and thoughtfulness in a way that is genuinely moving.
