Light Weight Key Facts

Light Weight Facts

What Weight Number Is Light Weight Yarn?

According to the Craft Yarn Council, it’s weight number 3 on the yarn weight chart.(1) 

What’s It Made From?

Most sweaters are made with either acrylic, cotton, wool, or a blend of the above. You can also find bamboo, pima cotton, mulberry silk, or baby alpaca.

Why Use It?

It’s easy to work with, as it knits up quickly because it’s a thicker yarn and you use larger needles. Light sweaters, afghans, accessories and baby garments are some options to choose from!

What If It’s Held Double?

If you want a heavier yarn, try holding two strands together. This increases the drape of the fabric.
