Crochet Basics Explained: Yarn Over, Yarn Under & UK vs US Terms

If you’re new to crochet, it can sometimes feel like everyone else speaks a secret language.

Patterns mention yarn over, yarn under, UK terms, US terms… and suddenly you’re wondering if you’re doing something wrong before you’ve even started.

The truth is: crochet has a few variations, and once you understand them, everything clicks into place. This guide breaks down the most common crochet techniques and terminology so you can crochet with confidence.

Yarn Over vs Yarn Under: What’s the Difference?

One of the first things beginners notice is that not everyone wraps the yarn the same way. That’s because there are two main methods used in crochet: yarn over and yarn under.

What Is Yarn Over (YO)?

Yarn over is the most commonly used method in crochet patterns.

• The yarn is wrapped over the top of the hook
• Pulled through the stitch

This creates:

• Slightly taller stitches
• A softer, more open fabric
• The standard look most patterns are written for

If a pattern doesn’t specify otherwise, it almost always means yarn over.

What Is Yarn Under (YU)?

Yarn under means bringing the yarn under the hook instead of over.

This method creates:

• Tighter stitches
• Smaller gaps
• A denser fabric

Yarn under is especially popular in amigurumi and plush crochet, where tighter stitches help prevent stuffing from showing through.

Yarn Over / Yarn Under Combinations Explained

Some crocheters use hybrid techniques to get a specific look or stitch density.

Yarn Over / Yarn Under (YO / YU)

This method means:

• Yarn over to pull up a loop
• Yarn under to finish the stitch

It creates a stitch that is slightly tighter than standard yarn over but still easy to work with — a popular choice for plush crochet.

Yarn Under / Yarn Over (YU / YO)

This method means:

• Yarn under to pull up a loop
• Yarn over to finish the stitch

This produces very tight stitches with excellent definition and minimal gaps, ideal for firm amigurumi pieces.

Does the Method You Use Really Matter?

Short answer: yes — but only sometimes.

The method matters most when:

• Working on amigurumi or plush toys
• Stuffing projects
• Following a pattern written for a specific technique

The most important thing is consistency. Switching methods mid-project will change stitch size and fabric texture.

UK vs US Crochet Terms: What You Need to Know

Another common beginner confusion is whether a pattern is written in UK terms or US terms.

The stitches are the same — only the names change.

This is why patterns usually state which terminology they use at the beginning.

How to Tell If a Pattern Uses UK or US Terms

• Check the pattern notes at the start
• Look for an abbreviation guide
• Notice stitch names like single crochet (US) or double crochet (UK)

Helpful Crochet Tips for Beginners

• Use stitch markers to track rounds and stitch counts
• Size up your hook if your tension is tight
• Don’t rush — consistency matters more than speed
• Choose smooth yarns so stitches are easier to see

Crochet Gets Easier — Promise

Every crocheter has moments of confusion at the start. Understanding yarn over vs yarn under and UK vs US terms removes a huge mental barrier and makes patterns far less intimidating.

Once these basics click, crochet becomes calmer, more enjoyable, and much more creative.
