How to Join a Crochet Hexagon Cardigan – Step-by-Step Assembly Guide

When Flat Crochet Pieces Become a Cardigan

This is the moment every crocheter waits for.

Your yarn is ready.
Your hexagons are complete.
Your granny squares are blooming.

And suddenly, everything comes together.

This step — joining all the pieces — is where crochet transforms from shapes into something wearable.
From flat geometry into a garment filled with warmth, meaning, and movement.

Just like Djerba itself: simple at first glance, deeply layered once you look closer.

Seamless joining is essential to achieve a fluid and professional finish. Each piece is carefully connected to preserve flexibility while maintaining strength.

This joining method is used throughout the Free Crochet Hexagon Cardigan , ensuring a clean and comfortable final result.

What You’ll Be Joining

Before we begin, let’s take a breath and see the whole picture.

Your crochet hexagon cardigan is made of:
2 large body hexagons (13 rounds each)
21 granny squares

Each piece already carries part of the story.
Now, we let them speak together.

Understanding the Two Panels: Right & Left

Each hexagon becomes one panel of your cardigan:
One is the right panel
The other is the left panel

Important Orientation Note

The left panel must be flipped horizontally after folding.
This is essential to ensure symmetry.

Think of it like architecture — balance matters.

Before joining anything, it’s essential to clearly understand the geometry of your hexagon.
This flat diagram shows each side numbered, the fold direction, and where sleeves and bottom extensions will be added.

How to Fold Your Hexagons (Key Step)

Once both hexagons are finished:
Fold each hexagon in half to create an L-shaped form

This fold naturally creates:
A sleeve opening
A body section

📸 You will see two visual layouts:
One for the right panel
One for the left panel (mirrored horizontally)

Identifying the Back of the Cardigan

This step is crucial for correct alignment.
Side 6 of the right panel
Side 4 of the left panel
➡️ These two sides will form the back of your cardigan
Once aligned, you’ll immediately recognize the silhouette.

Sewing the Panels: Points That Must Match

Now comes the precise but satisfying part.

Panel Seaming Instructions

For each panel:
Sew Side 1 to Side 3
Point 1 attaches to Point 2 (they become the same point)
Point 6 attaches to Point 3 (they become the same point)

This creates:
The sleeve base
The armhole structure

Take your time here.
This is where comfort is born.

Increasing Sleeve Length (Crochet Rounds)

Once the panels are folded, flipped, and sewn:

Adding Sleeve Rounds

Attach yarn at Point 1
Begin with a cluster stitch
Ch 1
Work (cluster, ch 1) into each ch-1 space around the sleeve opening
Sl st to join

➡️ Add 2 full rounds per sleeve
These rounds soften the sleeve edge and add balance to the garment.

Adding Granny Squares: Where Each One Goes

This cardigan uses 21 granny squares, each with intention.

Granny Squares for Sleeves

Sew 4 granny squares total for the sleeves
They extend and visually anchor the arm area

Granny Squares for the Back

Between:
Side 6 of the right panel
Side 4 of the left panel
➡️ Sew 4 granny squares to form the upper back panel
This section connects both panels gracefully.

Granny Squares for the Bottom Border

Sew 9 granny squares along the bottom of the cardigan
This creates:
Weight and drape Visual continuity
A beautifully finished hemline

Once the panels are folded and joined, the cardigan structure becomes much easier to visualize.
This filled layout shows exactly where each granny square is placed to form the sleeves, back panel, and bottom border.

Why This Construction Works So Beautifully

This method allows:
Natural movement
Easy size adjustment
A balanced distribution of texture

Hexagons bring structure.
Granny squares bring rhythm.
Together, they create harmony.

Can I change the number of granny squares?
Yes — especially at the bottom for length adjustment.

Do I need to block before joining?
Highly recommended for perfect alignment.
