Best Yarn for Amigurumi: Cotton, Acrylic and Blends Compared

The best yarn for amigurumi is smooth, tightly twisted and in a weight your pattern asks for. Beyond that, the fiber matters: cotton gives crisp stitches, acrylic is soft and easy to wash, and blends sit in between. This guide compares the common choices, explains how yarn weight changes the size of your toy, and shows how to test a yarn before you commit to a whole project.

What makes a yarn good for toys

• Smooth surface: stitches are easy to see and to count, and the surface does not hide mistakes.
• Tight twist (plied yarn): it does not split when you put the hook in, which matters with small hooks.
• Firm structure: it holds the shape of the toy, and the stuffing does not show easily.
• Washable: toys are handled and sometimes dropped, so washing instructions matter.
• Colorfast: dark and bright yarns should not bleed onto light parts when they get wet.

Fibers compared

Use light, plain colors for your first toys. Black, navy and other dark yarns hide the stitches, which makes counting and fixing mistakes much harder.

Yarn weight and the size of your toy

Yarn weight is how thick the yarn is. The same pattern worked in a thicker yarn with a bigger hook gives a bigger toy, and a thinner yarn with a smaller hook gives a smaller one. Most patterns state the yarn weight they were written for. Use it if you want your toy to match the size in the listing. If your yarn is a different weight, expect the finished size to change.

The hook should be smaller than the label suggests, so the fabric is tight. The sizes are in our crochet hook sizes chart.

Yarn for children's toys

For a toy that a child will hold, choose a soft yarn that you can wash, and check the label for the care instructions. Embroider the eyes instead of using safety eyes for babies and very young children. Rules on toy safety differ between countries, so check the ones that apply to you, especially if you plan to sell what you make. Our guide on how to stuff and assemble amigurumi explains the finishing steps.

How to test a yarn before you start

1. Make a small circle with a magic ring and 3 or 4 rounds, using the hook size from your pattern.
2. Look at the fabric in good light. Are the stitches clear? Can you see through the gaps?
3. Push a little stuffing behind it. If the white shows through the stitches, use a smaller hook or a firmer yarn.
4. Pull on the yarn gently. If it splits or breaks, choose a different one.
5. Wash the swatch if the toy will be washed, and check that the color does not run.

How much yarn does a toy need?

A small toy uses only a little yarn, often less than one ball. The pattern lists the amount, or the main colors needed, in the materials section. If it does not, buy a little more than you think you need for the main color, because a second ball of the same dye lot can be hard to match later. Our crochet patterns for beginners list the materials before you download.

Mistakes to avoid

• Using fluffy or textured yarn for a first project.
• Mixing yarns of different weights in the same toy, which makes the parts uneven.
• Buying yarn before you read the pattern's materials list.
• Ignoring the washing instructions on the label.
• Using a hook as large as the label suggests, which leaves gaps for the stuffing to show.
