The Medium Yarn category includes worsted, afghan, and aran weight yarns. Knit gauge for 4 inches of stockinette is 16-20 stitches on US 7-9 needles.
Worsted weight yarn is wonderful for knitting sweaters, scarves, mittens, leg warmers and afghans. Aran and worsted are sometimes used interchangeably but Aran yarns tend to be slightly heavier than worsted yarns.

Cascade Yarns 220 and Superwash 220, Plymouth Encore or Galway, Berroco Ultra Alpaca and Vintage, Ella Rae Classic, Noro Silk Garden just to name a few.
Next blog, we will discuss Categories 3, Light, and 2, Fine.
Bulky yarn will help you knit hats, heavy sweaters, jackets, afghans/throws, scarves and other specialty items quickly. Category 5 yarns are about twice the diameter of worsted weight yarn. This yarn works great when Category 6 and 7 yarns are too heavy for your project.
If you are just learning to knit or crochet, this yarn is great for your first projects because the stitches are easy to see and you get fast results.
Yarn types in this category are often made from wool, mohair, acrylic or wool/synthetic blends.
