🌟 Introduction: “Assembling knitted pieces… without losing the thread (or the motivation!)”

You've already found yourself with several knitted pieces... and that little voice saying: "Okay, I'll put them together tomorrow."
Then the day after tomorrow.
Then… never? 😅

We understand you SO MUCH.
We, Lenny and Louise, started knitting with our grandma and our aunt, and we can tell you one thing: sewing and assembly can transform a project... or transform it into an unfinished project in the sewing basket .

➡️ Good news: advanced modular knitting changes everything.
This is THE method for creating original, complex, modern shapes—without having to knit a garment in one piece, or struggle with imprecise seams.

In this article:
✨ Clear explanations
✨ A step-by-step guide you can follow even when you're tired
✨ Our tips tested on our own bosses
✨ Recommended models for you to train on

Hold on tight: you're about to discover how fun, creative and ultra-rewarding assembly can be .

🔍 Advanced modular knitting: what exactly is it?

Advanced modular knitting involves knitting several modules (pieces or geometric shapes) separately, then assembling them together to create a garment or accessory with complex shapes, without excessive sewing.
These modules can be:

▪️ squares

▪️ rectangles

▪️ triangles

▪️ slanted sections

▪️ texture or color panels

💡 Key takeaway : This is an ultra-creative approach, perfect for jacquard, intarsia, graphic shapes and modern designs.

🧩 Why adopt modular knitting? (And who is it for?)

Many believe it is reserved for “very advanced” knitters.
Spoiler alert: absolutely not! 🙌

✔ The advantages

▪️ Modularity = freedom : you create exactly the shapes you want.

▪️ Easier to manage : small modules → fewer meshes → fewer errors.

▪️ Ideal for testing colours (hello intarsia and stripes).

▪️ Clean and invisible assembly , even without being a sewing queen.

▪️ Perfect for recycling leftover wool .

🎯 For whom?

▪️ Motivated beginners and intermediate players

▪️ Advanced knitters who want to think outside the box

▪️ Fans of graphic and modern patterns

▪️ Those who like to understand “why it works” (hello analytical brains 💛)

💡 Remember : if you can knit a square, you can knit modularly.

🧶 The essential basics before assembling: our Knit-sis method 🧡

Here we explain exactly what we teach in our workshops—the method we use for Festi, Mondrian, Splashie and all our creative models.

✨ 1. Knit compatible modules

The secret: think about gauge, symmetry and knitting direction .

Checklist:

▪️ Same sample? ✔

▪️ Same tension? ✔

▪️ Same type of border? ✔

▪️ Same knitting direction (ideally)? ✔

▪️ Same material? ✔

✂️ 2. Clean and invisible assembly techniques

That's often what's scary. But I promise, it's simple.

The methods we recommend:

▪️ Mattress stitch sewing (invisible stitch)

▪️ Pick up stitches along a module

▪️ Grafting / Kitchener (for perfectionists 😉)

▪️ Edge-to-edge junctions

▪️ 3-needle assembly

🎁 A tip inherited from our grandma :

“If you pull too tight, it buckles. If you leave it too loose, it gapes. Look at your thread as if it were a hair: it should glide smoothly without forcing it.”

🎨 3. Choose the right shapes for a modern look

Modular design allows for some seriously fun designs:

▪️ angled panels

▪️ Mondrian-style color blocks

▪️ twisted modules

▪️ triangle games

🛠 Tutorial: Assembling complex parts step by step

Here is our method — the one we use ourselves.

🧵 Step 1: Block first, then assemble

Always.
Absolutely always.
Even if you're feeling lazy. 😇

For what ?
➡️ Your modules are sized correctly → clean and straight assembly.

🧵 Step 2: Align the modules using the markers

Our tips:

▪️ Placement of markers in the middle

▪️ Checks for right/left symmetry

▪️ Compare the lengths on a flat table

🧵 Step 3: Choose the correct assembly method

For two identical pieces → mattress stitch
For a panel and a side edge → pick up stitches
For a seamless seam → Kitchener

🧵 Step 4: Assemble from the center outwards

A method inherited from our aunt:

“Start with the heart, end with the wings.”
This prevents voltage fluctuations.

🧵 Step 5: Soft Finishing Touches

▪️ tuck the threads in with a slightly thicker thread

▪️ blocks a second time

▪️ Admire your masterpiece ✨

💡 Key takeaway : assembly is 50% technique, 50% patience.
