LANG Infinity Yarn

Infinity does the colorwork for you. As you knit, the yarn moves through a sequence of colors at irregular intervals and varying intensities, so the stripes never repeat. Even plain stockinette turns into a striking, painterly fabric.

The yarn is a soft single ply of extrafine merino, spun in a thick-and-thin style that adds gentle texture and movement. Simple stitch patterns and lace show off the color shifts best.

Because the color sequence changes over long stretches of yarn, Infinity shines in larger projects like sweaters, cardigans, blankets, and generous shawls. It’s also a cheerful pick for children’s garments, hats, cowls, and mitts, and it’s machine washable for easy care.

• Never repeats: Each ball shifts through its colors in a unique, irregular sequence.
• Extrafine merino: Soft enough for next-to-skin wear.
• Thick-and-thin texture: A single-ply spin adds subtle depth and movement.
• Easy care: Machine wash warm and lay flat to dry.
• Generous yardage: 284 yards in each 100g ball.

Infinity’s shifting colors look even better next to a solid. Use a coordinating solid for ribbing, cuffs, and button bands, or alternate it with Infinity in stripes. These worsted-weight yarns from our collection pair especially well:

• Round Mountain Fibers Willow Worsted: A hand-dyed 100% merino with a soft hand and drape. It’s the closest match to Infinity’s merino feel, so it works well for color-blocked sweaters where both yarns sit side by side.
• Cascade ECO+ Wool: A 100% Peruvian wool in a wide range of solid colors. Pull one shade from your Infinity colorway for ribbing, yokes, or alternating stripes in blankets and cardigans.
• Berroco Ultra Alpaca: An alpaca and wool blend with warm heathered solids. It’s a great anchor color for hats, mitts, and cowls, and the alpaca adds extra warmth.
• Cascade Pure Alpaca: A worsted alpaca with beautiful drape. Pair it with Infinity for shawls and wraps, using the solid for borders or wide stripes so the color shifts take center stage.
• Knitting for Olive Heavy Merino: A soft 100% merino in muted, Scandinavian-inspired tones. Its quieter palette tames brighter colorways like Rainbow Cascade or Pastel Pop.

What weight is LANG Infinity?
It’s worsted weight, knitting at 19 stitches per 4" on US 7–8 (4.5–5 mm) needles.

How many yards are in a ball of LANG Infinity?
284 yards (260m) per 100g ball.

Will my sleeves or socks match?
Probably not exactly. Infinity’s colors appear in an irregular order, so two pieces from the same ball will look related but not identical. That’s part of its charm.

How many balls do I need for a sweater?
Most adult worsted-weight sweaters take 4–5 balls, depending on size and pattern. Check your pattern’s yardage.

Can I machine wash LANG Infinity?
Yes. Machine wash warm on a gentle cycle and lay flat to dry.

What stitch patterns work best with self-striping yarn?
Stockinette, garter, and simple lace let the color shifts take center stage. Busy cables or textures can get lost in the changing colors.

What solid yarn goes with LANG Infinity?
Choose a worsted-weight solid in merino, wool, or alpaca. Match it to one shade in your Infinity colorway, or use a neutral for contrast. Round Mountain Fibers Willow Worsted, Cascade ECO+ Wool, and Berroco Ultra Alpaca all pair well.
