A classification of yarn exists, categorized by its thickness. This category, often favored for its versatility, occupies a middle ground between lighter and heavier yarns. The characteristic lies in its gauge, typically knitting at 5.5 to 6 stitches per inch on US size 5-7 needles. Examples of projects frequently employing this yarn weight include lightweight sweaters, baby clothes, and accessories like scarves and hats, where a balance of warmth and drape is desired.
The popularity of this yarn thickness stems from its adaptability to a wide range of projects and climates. Garments crafted from this yarn are generally lighter and more breathable than those made with thicker yarns, rendering them suitable for transitional weather. Historically, it gained prominence as hand knitting became more widespread and knitters sought yarns that were easy to work with and yielded aesthetically pleasing results without excessive bulk.
