Blue Yarn

Blue is the biggest color family on our shelves, so this page shows every in-stock blue colorway on its own card: navy, denim, cobalt, sky, teal, and turquoise, across wool, cotton, and sock yarns.

Blues that drift toward green are here too. For deeper greens see green yarn, and for violet-leaning blues see purple yarn.

Choosing a blue

Most blue yarn falls into three groups. Navy and indigo are the workhorse darks for sweaters and menswear. Mid blues like denim, cornflower, and cobalt are the ones people pick for a first sweater because they are easy to wear. Light and bright blues (sky, aqua, turquoise, teal) are where you get into baby things, summer knits, and colorwork accents.

Heathered blues, like the Cascade 220 heathers, have flecks of other colors spun in. They hide small tension changes well and look richer in plain stockinette than a flat solid does.

Blue yarns worth knowing

Navy is harder to knit than it looks

Very dark blues are almost as hard to see stitches in as black. Knit under a good light, use needles in a contrasting color, and put a light cloth on your lap. Your eyes will thank you on the cable rows.
