What size will the finished piece be?

The finished mermaid measures approximately 20-25 cm tall depending on yarn tension and yarn weight; the jellyfish is a small companion of around 6-8 cm tall with tentacles.

Can I use different yarn weights for this pattern?

Yes, you can use different yarn weights but it will change the final size; if you use a thicker yarn, increase hook size and expect a larger doll, while thinner yarn yields a smaller version.

Do I need prior crochet experience for this pattern?

This pattern is rated intermediate because it uses continuous rounds, BLO/FLO, bobble stitches, and assembly steps like sewing a wig; basic amigurumi experience is recommended.

How long does this project typically take to complete?

Most crocheters complete the mermaid and jellyfish in 5-7 hours, though time varies by experience, customization, and assembly care.

Assembly Instructions

Place 8 mm safety eyes on the head 9 sc apart between rounds 17 and 18, secure washers, and embroider eyelashes and nose as shown in photos.
Sew the wig to the head in the round where you made 24 hairs, pinning sections first and sewing separate groups of strands to shape the style.
Attach arms into the body openings indicated in rounds 71-72 by inserting the arm tops and sewing securely, then continue crocheting to join as described.
Sew the mermaid fish tail pieces to the end of the tail and shape with photos as reference, then attach small fins to the tip of the tail.
Wrap and tape folded electrical wire (16 cm) and insert into the neck as support before sewing the head to the body when using wire reinforcement.
Sew jellyfish tentacles to the lower base by fastening yarn as FLO on round 3 and making 21 chains for each tentacle, then secure to the base and attach to the head at round 18.

Important Notes

💡Work each round in a continuous spiral unless otherwise noted and use a stitch marker to mark the end of rounds for accurate counting.
💡Start stuffing gradually where indicated and continue stuffing as shaping requires to avoid lumps and maintain smooth contours.
💡When a BLO or FLO instruction is given, change to that method exactly to achieve correct placement of hair and decorative details.
💡If adding wire for support, follow the specified lengths and wrap/tape the wire before inserting to protect the crochet and avoid sharp edges.

This Mermaid and Jellyfish set is a delightful project that brings ocean charm to your crochet collection. Whether making a playmate or a decorative keepsake, the pattern gives you clear steps and beautiful photos to guide assembly. Have fun customizing hair colors, tail hues, and facial expressions to make each mermaid uniquely yours. 🧜‍♀️🧶✨
