How to make an amigurumi bigger or smaller?

Here are some recommendations for adjusting the size of an amigurumi, whether you want to make it larger or smaller.

1. Change the size of the yarn and hook:

   • Larger amigurumi: Use thicker yarn and a larger hook. For example, if you usually use medium-weight cotton yarn and a 3 mm hook, you could use thicker yarn, like bulky yarn or chenille (which also gives a soft and velvety texture), with a 5 mm hook or larger.
   • Smaller amigurumi: Use thinner yarn and a smaller hook. You could use finer crochet thread or even sewing thread for a super-mini amigurumi, accompanied by a suitably sized hook (such as a 1.5 mm hook or even smaller).

2. Avoid changing the pattern's scale:

   • Directly modifying the pattern to change the size is not recommended, as this could result in a disproportionate amigurumi or design errors. It is better to follow the original pattern and simply adjust the size of the yarn and hook.

3. Use double yarn for a larger size (optional):

   • Another option to make a slightly larger amigurumi is to use the same yarn you would normally use but double-stranded, with a hook one or two sizes larger. However, this can make the amigurumi stiffer to the touch, and it is not an ideal solution nor one I would recommend for significant size changes.

Additional recommendations:

• If you are a beginner, it is easier to work with thicker yarns and larger hooks because the stitches are more visible and manageable.
• To achieve the best result, try making a small swatch with the new yarn and hook size before starting the complete amigurumi. This will help you ensure that the final size will be as desired.

In summary, the best way to adjust the size of your amigurumi is to change the yarn and hook you use. This method is simple, efficient, and ensures that the amigurumi maintains its shape and proper proportions.
