How to choose the right yarn starting from the project (and not just the title)

When choosing a yarn, the most common mistake is starting with the wrong question:
“Do I like this yarn?”

The right question, however, is:
👉 “Is this yarn suitable for what I want to create?”

A good project always stems from the balance between end use, garment structure, and yarn characteristics. Let's see how to make the right choice, step by step.

1️⃣ Always start with the project, not the yarn

Before even looking at Nm, composition, or color, ask yourself:

• Is it a garment for everyday wear or for a special occasion?

• Should it be warm, light, breathable, or durable?

• Should it drape softly or hold its shape?

• Is it an accessory or a structured garment?

🔑 The same yarn can be perfect for a scarf… and terrible for a sweater.

2️⃣ Define the garment's end use

Some practical examples

• Scarf / Stole

  • soft hand

  • volume

  • elasticity

  • even loosely twisted yarns work well

• Sweater

  • balance between softness and durability

  • good shape retention over time

  • stable and regular yarn

• Hat

  • elasticity

  • shape memory

  • yarn that doesn't "give way"

• Elegant Garment

  • fineness

  • clean surface

  • worsted or well-twisted yarn

3️⃣ Choose the right fiber (before the count)

The fiber matters more than the Nm number.

• Cashmere

  • warm

  • light

  • very soft

  • ideal for garments worn directly against the skin

• Wool

  • durable

  • elastic

  • perfect for structured knitwear

• Recycled Yarns

  • more voluminous

  • less regular

  • ideal for casual and comfortable garments

• Cotton

  • less elastic

  • cool

  • great for summer garments, less so for structured ones

👉 Same Nm, different fiber = completely different result.

4️⃣ Evaluate the thickness based on the final result

The count (Nm) is important, but it should be interpreted in terms of the project.

• Fine yarns (high Nm)

  • light garments

  • elegant knitwear

  • clean surfaces

• Medium yarns

  • everyday use

  • versatility

  • good compromise between weight and warmth

• Chunky yarns (low Nm)

  • warm garments

  • rustic look

  • prominent stitches

⚠️ A yarn that is too thick can make a garment stiff.
⚠️ One that is too fine can appear poor and "flimsy".

5️⃣ Consider the yarn's structure

It's not just about "how thick" it is.

Also consider:

• twist (high = more compact, low = softer)

• number of plies (plied yarn is more stable)

• woolen or worsted

• regularity

👉 A stable yarn is essential for:

• sweaters

• garments that need to last

• machine knitting

6️⃣ Think about the technique (needles, crochet, or machine)

The same yarn performs differently depending on how it's worked.

• Hand knitting

  • requires elasticity

  • the hand feel is fundamental

• Machine knitting

  • regularity matters

  • pay attention to tension

  • the count must be compatible with the gauge

A yarn that's perfect on paper can become unmanageable if worked incorrectly.

7️⃣ Always do a swatch

It's the most underestimated, yet most important, step.

The swatch is for:

• understanding the actual drape

• seeing the hand after washing

• checking stability and drape

• avoiding irreversible mistakes

👉 The yarn "tells its story" only after it has been worked.

There is no universally perfect yarn.
There is the right yarn for that project.

Learning to choose by starting with the end result means:

• less waste

• fewer mistakes

• better garments

• greater satisfaction

Choosing a yarn is not about numbers, but about coherence between project, material, and technique.

When you learn to start with the project:

• the Nm becomes a tool

• the fiber a conscious choice

• the final result is never accidental
