Why You'll Love This LULU the mermaid Amigurumi Pattern

I absolutely love this pattern because it combines simple amigurumi construction with lovely finishing details that make each mermaid unique. I enjoy designing the wig and little buns because they add so much personality with minimal extra work. Sewing and modelling the eyes give the faces expression and character, which always delights me when a finished doll looks so alive. I also appreciate that the pattern includes colour codes for four different looks, so I can easily change the palette for new variations.

Switch Things Up

I love how easy it is to customise Lulu by swapping yarn colours for completely different moods โ€” try pastel shades for a soft baby mermaid or jewel tones for a dramatic look.

I sometimes change yarn weight and hook size to create a mini keychain version or a larger cuddle-sized doll; remember to adjust eye sizes when you do this.

I often add embroidered freckles, tiny sequins or metallic thread on the tail for sparkle โ€” these small touches give each mermaid a personality of her own.

You can make alternate hairstyles by crocheting longer hairstrands or braiding the hair strands before sewing them in place for a playful style.

I like to create little outfits: a tiny crocheted bikini top or a removable shawl can be fun for play and photo opportunities.

For a more baby-safe toy, I sew the wig and all small parts down tightly and use embroidered eyes instead of safety eyes.

Try adding a loop at the top of the head to turn your mermaid into a hanging ornament or a bag charm; a small metal ring works well for this.

I sometimes fill the tail with slightly firmer stuffing in the lower portion to help the mermaid sit upright when displayed.

You can mix-and-match features from the four sample dolls in the colour codes to create new colour combinations and unique characters.

If you want posable limbs, consider adding thin craft wire inside the arms before sewing them closed, taking care to anchor the wire ends safely inside the body.

Common Mistakes & How to Fix Them

โœ— Skipping stitch markers during rounds can lead to losing your stitch counts; place a stitch marker at the start of every round and move it each round to track your position accurately. โœ— Understuffing the head results in a floppy shape while overstuffing causes visible holes; stuff gradually and evenly, checking the shape often to keep a smooth round form. โœ— Forgetting to change colour at the correct point can make seams obvious; work the colour change at the end of the previous stitch leaving two loops, then yarn over with the new colour and finish the stitch. โœ— Not checking eye placement may make the face look unbalanced; attach the safety eyes between rounds 16 and 17 with a distance of 11 visible stitches for the recommended look.

โ€” Tips before starting :

Infos :

When using similar or the same yarn with the same hook size, the mermaid will be approx. 26 cm tall. When you need to decrease, make Invisible Decrease crochet stitches to have a neater result. Please be aware that when you use different yarns and hook sizes, the outcome may vary and you may have to adjust the size of eyes. Colour change is worked at the end of the previous stitch. Work the last stitch before the colour change as usual but don't complete the last stitch. When you have 2 loops on your hook, yarn over in the new yarn colour and finish the stitch. Continue working with the new colour.

Continue to stuff the head, especially in the neck area (if you use a piece of a foam curler to stabilize the head which is explained later, you can leave the neck area unfilled). The head should be filled evenly without any bulges and it should have a complete round form. But also be aware to not fill too much. When you notice that the stitches stretch and the holes between them get bigger so you can see the polyfiber fill through them, then you have stuffed too much. In this case remove some of it.

โ€” Wavy hem :

Info :

Colour D. Take the yarn and make a standing sc into the first front loop of rnd 28 of the tail. Continue as follows: (skip 2 sts, 5 dc into a st, skip 2 sts, 1 sc into a st) x 5 (in the last unit just skip only 1st, so that you achieve 6 waves all around). Crochet 1 sl st into the first sc of the previous round. Cut the yarn, fasten off and sew both threads carefully.

โ€” Flower in the hair :

Info :

Colour E. Start with a MR (leave a long starting yarn tail). (1 sc, ch 2, 1 sc into 2nd chain from hook) x 5. Sl st into the first st. Cut the yarn and fasten off by pulling the tail of yarn until the MR is closed. Sew the thread. With pink blush and a brush paint the centre of the flower with a pink dot. Alternatively you can crochet several flowers to make a flower crown across the hair line (as you can see on doll 3).

โ€” Modelling the eyes :

Info :

After you have crocheted all body parts, you can now start to shape the eyes by bringing the eyes inwards. Take a sharp sewing needle and a long thread of colour A. Pull both ends of the thread through the head very close to the eye and bring them out at the head opening. Take one of the thread ends and repeat the same with the second eye. Pull on both thread ends as tight as possible until the eyes move inwards. Knot both ends very tightly. At the end stuff both threads into the head. If necessary you can now add some more stuffing into the head with the help of the end of the crochet hook.

โ€” White of the eye :

Info :

Once the eyes have been modelled, you can add the white of the eyes to the outer edge of the eye. Use a long cotton thread in a white colour and embroider a small stitch at the outer part of the eye. Repeat these steps on the second eye as well. Knot the ends at the bottom of the head and stuff the threads into the head.

โ€” Eyebrows :

Info :

Take a thin sewing or embroidering yarn in colour black or brown and a thin sharp needle. Embroider the eye brows 2 rounds above the eye, diagonally over 1,5 stitches. (Or alternatively as you can see at doll 4 embroidered directly over the eye, diagonally over 2,5 stitches).

โ€” Nose :

Info :

For embroidering the nose cut a long tail from colour A. Between rnd 16 and 17 you can embroider 2 horizontal stripes, running over 2-3 sts. Don't sew the thread but wrap it with the needle tightly around the horizontal stripes. At the end take a small brush and put some pink blush onto the cheeks of your mermaid.

โ€” Sewing the hair parts (plus optional the ears) :

Info :

Put the hair wig onto the head of your mermaid. Be sure that it is symmetrical around the head and at the right distance from the eyes. If the doll will be played by a small child, you can now sew the wig onto the head with some sts. Otherwise it's not necessary to sew it as the wig is quite tight on the head. In this case just sew the thread carefully. Now you place the 2 hairstrands symmetrically across the hairline and pin them. For sewing them you can either use one of the remaining threads or a thin sewing thread and a thinner needle. But be sure to take a very long sewing needle which makes it easier for you (for reference: my needle is about 6-7 cm long). Start to sew the first strand beginning at the top downwards, ending approximately at the level of the eyes. Make the same with the 2nd hair strand on the other side of the head.

โ€” Sew both buns :

Info :

Now sew both buns. Position them below the hair strands at the hair line and fix them with pins. Sew them around all 9 sts from the last rnd of the bun. Sew the thread carefully.

โ€” Ears (if chosen) :

Info :

If you have chosen to crochet the ears, you can now sew them at eye level directly next to the hair line. Use both threads of the ear above and below for sewing. Sew the threads carefully.

Assembly Instructions

  • Attach the head to the top opening of the body and sew securely using the long tail left from finishing the head; position so the wig hairline aligns with the body top and stitch evenly around the neck.
  • Place and sew arms to the sides of the body between the specified rounds (use photos as reference), flattening and overlapping the base where indicated and securing with long stitches for strength.
  • Sew both fins to the lower tail opening, aligning the fin base with the tail's end and stitching evenly around the join; do not stuff the fins prior to sewing.
  • Position the wig symmetrically on the head and sew in place if the doll will be handled by small children; pin hairstrands and buns before sewing to guarantee symmetrical placement and stitch securely.
  • Add wavy hem edging into the front loops at round 28 of the tail and sew carefully; then sew flowers and any other small accessories to the hairline as desired.

Important Notes

  • ๐Ÿ’กUse stitch markers to keep track of your rounds, especially when working many consecutive rounds on the tail and head.
  • ๐Ÿ’กStuff firmly but not too tightly for the best shape and structure; overstuffing can distort stitches and show polyfill through the fabric.
  • ๐Ÿ’กWork the colour change at the end of the previous stitch: do not complete the last stitch, yarn over with the new colour and finish to secure a neat join.
  • ๐Ÿ’กSew on wig and small parts carefully and use longer needles for threading hairstrands to avoid tangling and misplacement.
