How to make a knitted turtleneck for a trendy sweater? 🧶✨

Knit Sis

Introduction: The detail that changes everything

Dreaming of a cozy, modern, and stylish sweater? The turtleneck is THE chic and practical touch that transforms a simple knit into a trendy piece. But... how do you knit a turtleneck that fits well, without bunching or suffocating?
We, Lenny & Louise, have tested dozens of versions of our sweaters and cardigans. Today, we're sharing our knitting sister tips for successfully knitting a turtleneck – even if you're a beginner. 🤗

Why choose a turtleneck?

A turtleneck isn't just a tube of knit. It's:

▪️ Warmth & comfort : goodbye drafts in the neck!

▪️ Timeless style : from retro chic to minimalist Scandinavian vibes.

▪️ Easy to adapt : ​​it can be knitted short, long, fitted or loose.

💡 Anecdote: Our grandmother always said that “the turtleneck is the scarf that never gets lost.” She made us one every winter… and we’re continuing the tradition, but in a more modern and cheerful version. 🌈

The technical basics for knitting a turtleneck (stress-free) 🧵

1. When to pick up stitches?

Generally, you knit the sweater or cardigan up to the neckline, then pick up the stitches all around the collar .
👉 Knit-sis tip: Use a smaller circular needle (0.5 to 1 mm smaller) than the body needle. This prevents the collar from “gaping”.

2. What height of turtleneck should I choose?

▪️ Short (5-8 cm) : modern and light, perfect on a sleeveless sweater like Cuddly .

▪️ Medium (10-15 cm) : the most versatile, ideal on a sweater like Strippie .

▪️ Long (20-25 cm) : for a cozy cocoon effect, like a Doudou sweater.

📌 Remember: the longer the neck, the softer and more flexible the thread is to avoid a “cardboard” effect.

3. Which stitch to use?

The 1/1 or 2/2 ribbing remains the simplest and most elastic.
But if you want a sophisticated look, try:

▪️ English ribs (puffing effect),

▪️ or an intarsia-style color scheme for a fun style (like our sweater Splashie ).

Common mistakes to avoid 🚫

❌ Knit with the same needle size as the body → collar too loose.

❌ Picking up too few stitches → tight collar that pulls on the neckline.

❌ Forget the elasticity of the thread → some threads like cotton lack hold.

💡 Knit-sis pro-tip: before knitting the entire collar, test 5 rows . If the tension or the result doesn't suit you, you won't have wasted an hour 😉.

Modern variations for a stylish turtleneck ✨

Turtleneck with lapels

Double the height to fold it up. Ultra cozy, perfect over a cardigan like Festive .

“Tube” turtleneck

No decreases or cuffs: it folds naturally. More relaxed.

Fitted turtleneck

By reducing the number of stitches, we obtain a very chic result (second skin style).
