Worsted & Aran Weight Knitting Yarn & Wool
Worsted weight yarns and aran weight yarns are similar, but different weights although sometimes interchangeable for patterns. A worsted weight yarn is finer and calls for 4.5mm needles, where aran weight yarn is slightly heavier, and calls for 5mm needles. Aran yarn is sometimes known as heavy worsted weight or 10ply, too. For fast finish knits, aran and worsted yarns bring drape and wearability but knit up fast! A great choice for garments, accessories and home decor.
