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. (Products are 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 depending on the manufacturer.

  • AKA – Light Fingering 
  • Weight Category – Lace
  • Weight Number – 0
  • Wraps Per Inch (WPI) – 30-40+(4)
  • 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 Number is Lace Weight Yarn?

According to the Craft Yarn Council, Lace Weight Yarn is Number 0.(1) It’s for delicate projects! It’s the finest yarn category and the Number scale starts at 0.

Yarns In This Category

Here are the different types of lace yarn.

  • Cobweb – It’s for delicate cobweb lace and is only 1-ply
  • Size 10 Crochet Thread – Super thin thread for crocheting on steel hooks

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, and 70% Baby Alpaca, 30% Merino.

Rarer, but sometimes you’ll find kid mohair yarn, cashmere or baby alpaca fibers, or a blend of those. The selection of the more expensive fibers are beautiful to knit with if they are within your budget.

It’s often quite pricey so it is a good idea to purchase when on sale. Buying larger quantities may receive a discount. One tip is to sign up to your favorite yarn store’s newsletter to keep in the loop of upcoming offers. That way you don’t miss out!

Why Use It?

It’s great for lacy summer projects because it’s airy. It’s also an ideal choice for lace projects with the lovely characteristics of softness and sheen. Remember some people find it impossible to use as its so delicate and fiddly. You need to be patient!

When you are winding your skein into a ball, take particular care to go slowly. There’s a tendency for these yarns to get tangled when you create a ball. An idea I tried was to hold together fine mohair yarn with other bases to add texture and softness. This makes a bit thicker yarn and easier to knit.

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, swatch first because the gauge will be different.

Uses For This Yarn

There are endless possibilities for this soft, loftily spun and plied yarn. Here are ideas for lace weight yarns to start with. Items like shawls, table runners, lace projects, hats, delicate and lightweight garments, doilies, tops, mandalas, and summer projects like summer tops and cardigans.

Large projects like wraps often feature designs of geometric shapes. It’s one of the ways of showing off color and form! When you experience the finest merino wool, the high quality texture makes for a luxurious knitwear item.

Some yarns have a silk core with a halo of mohair. Anyone who has received gifts of this type of yarn can attest to the sheer luxury.

Lace Weight Yarn Patterns To Try

Here are lace weight yarn patterns. They feature wraps, scarves, shawls and sweaters. All these patterns have clear directions.

Looking for another shawl pattern? See the below video by Chandi from Expression Fiber Arts for inspiration. Chandi showcases her lace patterns.

Her Shunki Wrap has a lace design worked on the right side only, which is a plus. A lovely lightweight garment.

What Knitting Needles To Use

Here are the best tools to use with this.

  • US Needle Size – 000-1
  • For those of you in Canada, UK, Australia and New Zealand use Metric Needle Size – 1.5-2.25mm

Note: The above are guidelines only. Always swatch before starting a project.


If you’ve run out of this yarn or can’t find it, use fingering weight instead. (It’ll be slightly thicker, so test your gauge.)

FAQS About Lace Weight Yarn

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, particularly of hand dyed yarns.

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/balls (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?

It 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, and Lana Grossa, and Manos del Uruguay.

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.

A great sort of yarn for crocheters too! A small diameter hook is used with super fine yarns. Fine cotton thread is used to make delicate crocheted items.

Another option for somewhere to buy, are small businesses on Etsy selling handmade dyed yarn. Creating an account there in your own currency, gets you the best deals. There are Etsy sellers from all over the world including Belgium, Japan and Italy.
