Worsted or Aran Weight Yarns
Worsted weight yarn is the most widely available weight of yarn and the most frequently used. At double the weight of fingering yarn, worsted weight yarn is great for knitters of all skill levels and can be worked into nearly anything. Heavy worsted weight, as you may have guessed, is just slightly heavier than worsted weight and is good for the same range of projects as worsted weight. Worsted weight averages a knit gauge range of 4-4.75 stitches per inch in stockinette stitch on a US 7-9 needle.
