Knowing Your Yarn Weights

The weight is a great place to start to know the thickness and also what that yarn can be used for.

When choosing yarn for your next project, it is important to know how to adjust knitting pattern instructions if you want to use a different type of yarn than the one that has been suggested on your pattern.

Not every yarn can be used for just any project, but knowing about yarn weights will allow you to choose what you want and know the effects it will have when you start to knit or crochet.

It’s always a good idea to work up a gauge swatch before you start a project that involves sizing.

This is because not all yarns of a certain weight are the same.

How Do I Know If My Yarn Is Fine?

Everything you need to know about your yarn, you will find on the yarn label.

The yarn manufacturer provides all the necessary details about your yarn.

Yarns that are mass-produced will have that information on the label using the yarn standards system from 0-7.

From the weight, the yardage, the fiber content, and the size of hooks, and needles you will need for this specific yarn.
