What Is Lace Weight Yarn?

Lace weight yarn is the lightest weight of yarn in the Craft Yarn Council standards system.

The number for this yarn weight is 0.

(Commonly misspelled as lace weight yan.)

To be considered lace, a yarn must have a gauge of 33-40 stitches over 4 inches on US size 000-1 needles.

This is the lightest and most delicate yarn weight, and it’s difficult to find in chain craft stores.

The ply varies widely, depending on the manufacturer.

  • AKA – Light Fingering 
  • Weight Category – Lace
  • Weight Number – 0
  • Wraps Per Inch (WPI) – 30-40+
  • Ply – 1, 2 or 3
  • Knitting Gauge – 33-40 stitches over 4 inches
  • It’s thicker than some crochet threads
  • It’s thinner than all other yarns

It’s important to note lace weight yarns are often knit on larger needles than US000-1 to create a more open lace pattern.

Always swatch to test your gauge matches the pattern.

What’s It Made From?

Any fiber content (fibre), but primarily a base of wool or fine merino wool or mulberry silk.

Blends of the two are most common.

Common ones include

  • 100% Merino
  • 70% Wool, 30% Silk
  • 70% Baby Alpaca, 30% Merino

Rarer, but sometimes you’ll find kid mohair yarn, cashmere or baby alpaca fibers, or a blend of those.

Why Use It?

It’s great for summer projects because it’s airy. It’s also an ideal choice for lace projects with the lovely softness and sheen.

Remember some people find it impossible to use as its so delicate and fiddly. You need to be patient!

Once you learn to create with fine yarn, it’s a treat to use!

What If It’s Held Double?

If you double it (knitting with two strands at once) it will become like fingering weight yarn.

If you do this for a creation, swatch first because the gauge will be different.

How Do You Spot Lace Weight At Craft Stores?

It’s tough to find it in stores.

Few big brand craft shops have them in stock, and availability depends on the country the shop is based in.

Dedicated local yarn shops will have a much better range.

Here’s what to look for.

  • It will be with the other fine weight yarns
  • The skeins are small
  • There isn’t many yards per skein (called yardage)
  • It’s thinner than other yarns
  • The colors are sometimes in pastel or light shades

Keep in mind to buy everything you need for one project in one go, as lace yarns are done in dye lots.

How Popular Is Lace Weight Yarn?

Itt isn’t as popular as other yarn weights because it’s difficult to find and it’s the lightest weight.

It’s also best suited to experienced knitters because it is often used for complicated lace knitting patterns.

It is often difficult to “frog” as in undo your work as the fine fiber can get easily tangled.

Popular luxurious yarns for making beautiful projects and accessories come from companies like

  • Knit Picks (also sells supplies like pattern books)

Here are brands I recommend.

  • SweetGeorgia Yarns
  • Malabrigo
  • Hedgehog Fibres
  • Lana Grossa

They have shipping options to several countries all over the world, including the United Kingdom, for a reasonable price.

Sometimes they offer free shipping to the United States. See the website for more information.

They’re great for crocheters too!

Another option are small businesses on Etsy selling handmade dyed yarn. Creating an account there gets you the best deals.
