Free Crochet Pattern: Barbie Cobble Stitch Mermaid Tail

By Claire Golden – 2 Comments

For many kids, the most fun part of playing dolls is dressing them up. This mermaid tail is an especially fun outfit that can be enjoyed by both kids and older doll collectors. It uses the cobble stitch, a pattern of alternating single and double crochet that’s much easier than it looks. The stitch makes the tail durable for many afternoons of play, and you can use any color combination you like for a variety of looks. You could even include a mermaid tail along with a Barbie doll for a unique gift.

Skill Level:

Finished Size: Fits standard 11.5″ (29 cm) Barbie doll (with the belly button). Please note that there are various Barbie body types on the market today such as “Curvy,” “Tall,” and “Petite.” This pattern is designed for the classic body type because it’s the most widely available.
Tail measures approximately 10.5″ (27 cm) to end of fins.

Materials:
Medium Weight Yarn in 2 colors (approximately 30 yards of main color for tail and 15 yards of contrasting color for shirt and fin color)
Crochet Hook F (3.75 mm)
Yarn needle
crochet yarn size 4

Gauge:
10 sts (in cobble stitch) = 2″
9 rows = 2″
Gauge Swatch: 2″w x 2″h (5 cm x 5 cm) ch 11.
Row 1: sc in second ch from hook, dc in next ch, (sc in next ch, dc in next ch) across: 10 sts
Row 2 – 9: ch 1, turn, (sc in next st, dc in next st) across: 10 sts
Finish off.

    I made this to the T and it did not fit my barbie at all. I have 3 barbies of the exact same standard size with regular barbie clothes and the tail went all the way above the chest of my barbies with room to spare and had about an inch space between the hips/waist and the tail. The top was too big as well. I want to crochet this tail for my nieces but it’s hard to do when either the pattern is wrong or the hook and yarn size is wrong. I will try to figure it out but i thought i would let you know

      Hi April, I’m sorry you’re having trouble with the sizing! I went to double-check the pattern and the hook and yarn I used are correct. I am a pretty tight crocheter, so if you’re a loose crocheter, you’ll probably need to go down a hook size or two. Did you check gauge? And just to confirm, this tail won’t fit the original Barbie body type with the super-tiny waist, it’s made to fit the belly button Barbie type. I’m guessing that’s the one you’re using, but never hurts to check again 🙂 I hope you have better luck this time!
