🏷️ How to read a wool label: decoding it so you never make a mistake again

Introduction

When faced with a skein or ball of yarn, it can sometimes be difficult to find your way around: weight, yardage, needle size, dye lot… Yet, knowing how to read a yarn label is essential to succeeding in your project, avoiding mistakes in size or texture, and choosing the right yarn — especially when investing in beautiful hand-dyed wool.

1. Weight and yardage: how much yarn do I really have?

🧮 Typical example:

• 100g – 400m → fingering yarn

• 100g – 200m → worsted

• 50g – 100m → DK

👉 It is the weight / length ratio that determines the yarn category: lace, fingering, sport, DK, worsted, bulky, etc.

➡️ A 100g skein can be very thin or very thick depending on how many meters it contains!

2. Recommended needle / crochet hook size

The label often indicates a range of needle or hook sizes (e.g., 3.5 – 4.5 mm), but:

• This is not a strict obligation, just an indication.

• You can adapt it according to your stitch, your tension, or the desired effect (looser or denser).

3. Recommended gauge

Often indicated as follows

💡 This means that with the recommended needles, you get this 10 cm square.

➡️ Always knit a gauge swatch, especially for fitted projects like a sweater.

4. Fiber composition

Example:

• 100% Merino

• 75% Merino – 25% nylon

• 80% BFL – 20% silk

🧠 Things to remember:

• Nylon adds durability (ideal for socks).

• Mohair gives a fuzzy and airy effect.

• Silk or bamboo add shine and drape.

➡️ Hand-dyed yarns often have a richer description than industrial yarns: base, origin, treatments (e.g., Superwash), etc.

5. Dye lot: not to be overlooked!

Same shade = yes, but sometimes slight variations appear between two dye lots.
Especially with hand-dyed wool: each lot is unique.
📌 Advice: always buy enough yarn from the same dye lot for your project.

Conclusion

A yarn label is a true identity card. Learning how to read it allows you to choose your yarns better, avoid costly mistakes, and make the most of your skeins — especially if they come from a dyer you adore 💖
