It’s happened to all of us: you start an amigurumi project, you have the perfect yarn, the idea is clear… and suddenly the little doll turns out loose, full of gaps, or stiffer than you wanted. And that’s when the existential doubt hits: “Maybe I used the wrong hook?” Believe me, you’re not alone. Choosing the right hook is one of those small details that makes all the difference, even though no one tells you this in the beginning.
Why the hook is so important in your amigurumi
When we crochet amigurumi, we want the fabric to be firm, even, and without gaps where the stuffing could peek out. And although yarn is essential, the hook plays a major role in tension and in the final finish.
Plus, using the right hook helps you:
- Crochet more comfortably.
- Avoid hand pain after a while.
- Achieve cleaner stitches.
- Maintain consistent sizing between pieces (crucial when making dolls with multiple parts).
And yes, sometimes simply going down half a size can change the fabric completely.
How to know if your stitches are too loose
If you see gaps between stitches, if the stuffing shows through, or if the piece loses shape, the hook is too large. This often happens to people who come from crocheting garments or blankets, where softness is the priority.
How to know if it’s too tight
If it’s hard to pull the hook through, if the yarn splits, or your finger starts hurting from pushing so much, you’re using a hook that’s too small. A firm fabric is good… but we don’t want to suffer either.
Types of hooks for amigurumi and which one suits you
This is where it gets fun, because there are many options, and choosing yours depends on what feels most comfortable.
Aluminum hooks
These are the most common. They’re lightweight, glide well, and are usually inexpensive. They work perfectly for most amigurumi projects, especially if you’re just starting out. You can find them in specialized shops or on pages like
Katia.
Ergonomic hooks
They have a thicker, softer handle that helps prevent hand fatigue. If you tend to crochet for long periods or already have discomfort, they can be lifesavers.
Steel hooks
They’re very precise and ideal for very thin yarns. Although they’re used more in fine lacework, some people prefer them for small details in amigurumi.
Hooks with silicone handles
They combine the precision of traditional hooks with the comfort of ergonomic ones. They’re a middle ground many crocheters love.
Which hook size to choose depending on the yarn
Although every brand recommends a size, for amigurumi we almost always use a smaller hook than the label suggests. This helps keep the fabric firm.
Here’s a quick guide:
- Thin yarns (like 2 mm mercerized cotton): hooks between 2.0 and 2.5 mm.
- Medium yarns (like 3 mm cotton): hooks between 2.5 and 3.0 mm.
- Thick yarns: hooks between 3.0 and 4.0 mm, depending on the effect you want.
The best thing is to make a small test swatch. If the fabric is firm and without gaps, you’re on the right number.
When the yarn suggests one number, but the doll needs another
Sometimes the label says “4 mm hook,” but if you use it for a doll, it turns out huge and loose. In that case, you can go down even two sizes and it’s totally fine. What matters is that it feels compact.
As a reference, many crocheters who make professional amigurumi use smaller hooks than you’d expect, precisely to achieve that firm texture characteristic of these pieces.
Practical tips for choosing your ideal hook
Here are some tricks that aren’t always mentioned, but help a lot:
Test the hook before starting the project
Crochet a few stitches and check:
- Does the yarn glide well?
- Do you feel like you’re forcing the hook out?
- Are there gaps?
- Does your hand hurt?
If anything like this happens, try a different size.
Don’t stick to just one brand
We often think all hooks work the same, but they don’t. Some have sharper tips, others more rounded, and that affects how you grab the yarn. For example, brands like
Clover
are well known for their comfort, but every hand is different.
For small details, use thinner hooks
If you’re embroidering little eyes, making tiny ears, or very small accessories, going down half a size can help you achieve more precision.
Check the hook tip type
Sharp tip: perfect for compact yarns and tight stitches.
Rounded tip: ideal if your yarn splits easily.
Listen to your hands
If your wrist hurts, if you feel tingling, or if it’s hard to keep going, the problem might not be your “technique,” but the hook. An ergonomic one can change your entire experience.
Common mistakes when choosing hooks for amigurumi
Yes, we’ve all been there. And it’s okay. The important thing is identifying it so your future projects turn out the way you imagine.
Using the hook you normally use for garments
This is a classic. Since we’re used to crocheting softly, we keep the same hook size… and the amigurumi ends up less firm.
Forgetting that every yarn behaves differently
Combed cotton, mercerized cotton, or yarn blends with acrylic don’t behave the same. Even if the thickness is similar, their rigidity changes.
Starting a new project without testing first
I know sometimes we get too excited to see the doll take shape, but making a quick swatch is what will save you from unraveling everything later.
How to know when you’ve found the perfect hook
When the fabric flows without fighting you, when the doll is firm but not “hard,” when there are no gaps and your hand doesn’t get tired… that’s it. And believe me, once you find it, you won’t let it go.
Many of us end up having a “favorite hook” that we use for almost everything. Even if it’s not the prettiest or the most expensive, it’s the one that feels just right.
If you’re just beginning to explore this world or if you’ve been crocheting for a while, tell me: what hook size do you use most for your amigurumi? I’d love to read your answer.
