Sport weight yarn is a fine weight yarn that falls in between fingering and DK weight yarns. It’s ideal for lightweight garments like hats, socks, mittens, light sweaters, shirts, and baby clothes. It’s also a perfect choice for colorwork.
Sport weight yarn is often thought to be interchangeable with DK yarn, but there’s a slight difference in thickness. If you’re thinking of using a sport weight yarn in a pattern that calls for DK, we recommend playing around with needle size until you get the gauge just right.
