Aran & Worsted Knitting & Crochet Yarn & Wool
Aran weight yarns and worsted weight yarns are often interchangeable, but actually different weights. Worsted weight yarn is finer and knits on 4.5mm needles, and aran weight yarn is knitted on 5mm needles. Aran weight yarn is sometimes known as heavy worsted weight or 10ply, too. If you love a speedy knit or crochet make, aran and worsted weights bring all the drape of a finer yarn but work up faster than their lightweight cousins. Ideal for crochet and knitted garments, accessories and homeware.
