What Is Noil and What Can You Do With It?

You finish a combing session and look at the pile of short fiber left behind on the tines. It's not the smooth, aligned combed top you were working toward — it's scrappier, shorter, a little tangled. And your first instinct might be to toss it.

Don't. That pile has more potential than it looks.

Anyone who has used wool combs has seen the short fiber that remains behind after combing. This material is called noil. While some spinners initially view noil as waste, it can actually be a valuable fiber preparation in its own right. This guide explains what noil is, why it appears during combing, and how spinners can use it in different fiber projects.

What Is Noil and Why Does Combing Produce It?

Noil is the collection of short fibers left behind when wool is combed. During the combing process, the longer fibers transfer between combs and become aligned for spinning. Shorter fibers, debris, and second cuts remain on the combs and form the noil. Noil typically contains short staple fibers, second cuts from shearing, small bits of vegetable matter, and fibers that are too short to align with the combed top.

Combing produces noil because the process is specifically designed to separate fibers by length. As the fiber transfers between combs, the tines catch and move the longer fibers while the shorter ones — those that don't have enough length to grip and transfer cleanly — remain behind. This selective separation is what gives combed top its smooth, parallel structure and makes it draft so cleanly during spinning yarn on a Turkish drop spindle. Noil is the inevitable result of that selection process — a higher noil yield simply means the combs did a thorough job of separating long from short. Learn more about how staple length affects combing.

How Much Noil Is Normal?

The amount of noil produced varies considerably depending on the fiber. Long wool breeds like Lincoln and Leicester Longwool typically produce very little noil because most of the fiber is long enough to transfer cleanly. Medium staple wools like Corriedale produce a moderate amount. Short staple wools like Merino produce more noil because a larger proportion of the fiber falls below the transfer threshold. Fleece with many second cuts — very short fibers from a second pass of the shears — will also produce more noil.

If you're producing what feels like an unusually large amount of noil, short staple length or second cuts are usually the cause. Learn more about how short and long staple fiber differ for combing.

Is Noil Waste? What It Can and Can't Do

Noil is not waste — even though it can't be used for smooth worsted spinning. It still contains real wool fiber that can be put to good use in a variety of ways. Silk noil — the short fiber byproduct of silk processing — is actually sold commercially as a desirable blending fiber, which gives a sense of how valuable short fiber byproducts can be. Wool noil deserves the same respect: it's a different material with different properties, not a failure of the combing process.

Because the fibers are shorter and less aligned, noil behaves differently from combed top. Instead of producing smooth yarn, it often creates softer, loftier fiber preparations. Noil from long wool breeds like Lincoln or Wensleydale tends to be relatively long for noil and often has a lustrous, silky quality that makes it pleasant to spin or blend. Noil from fine wool breeds like Merino is much shorter and finer, producing a softer, fluffier noil that felts easily and blends well with other fine fibers.

What You Can Do With Noil

Many spinners save noil for a variety of projects. Noil can be spun into woolen-style yarn — because the fibers are shorter and more randomly oriented, the resulting yarn is soft and airy rather than smooth and strong. Some spinners card the noil first to open and organize it before spinning, which makes drafting easier and allows blending with other fibers. Adding a small amount of silk, alpaca, or longer wool to the noil during carding can improve the drafting quality and add interesting texture or sheen to the finished yarn.

Noil also works well for felting because the short fibers entangle easily — both wet felting and needle felting are good uses for noil. Some spinners intentionally include noil in yarn to create slubs or textured effects. And noil can be used for stuffing handmade toys, ornaments, or small fiber crafts where the short fiber length is not a limitation. The key is to think of noil as a different material with different strengths rather than a lesser version of combed top.

Collecting and Storing Noil

If you plan to save noil, store it separately from your combed top so the two preparations don't mix. A simple paper bag, cloth bag, or lidded container works well. If you're collecting noil from multiple combing sessions to use later for blending or woolen spinning, keeping it in a dedicated container makes it easy to accumulate enough to work with. Label the container with the fiber type if you're working with multiple breeds, since noil from different wools will have different characteristics. Noil stores well as long as it's kept dry and away from pests.

Some spinners collect noil from many sessions before using it, building up a supply for a specific project. Others use it immediately after each combing session. Either approach works — the main thing is to keep it organized so you know what you have and can use it intentionally rather than letting it accumulate without a plan.

Making the Most of Every Combing Session

Thinking of noil as a useful byproduct rather than waste changes how you approach the combing process. Instead of feeling frustrated when the noil pile grows, you can see it as a sign that the combs are doing their job — separating long from short, creating clean combed top on one side and a usable short fiber preparation on the other.

The best combing sessions produce two things: smooth, aligned combed top ready for worsted spinning, and a collection of noil ready for its own set of projects. Both have value. Both deserve to be saved and used. That's the full return on a combing session — and it's one of the things that makes hand fiber preparation so satisfying.

Key Takeaways

• Noil is the short fiber left behind on the combs after longer fibers have transferred away — it is a natural and inevitable byproduct of the combing process, not a sign of poor technique
• Combing produces noil because it is designed to separate fibers by length — the tines catch and move longer fibers while shorter ones remain behind, giving combed top its smooth, parallel structure
• The amount of noil depends on the fiber — long wool breeds produce little noil, medium staple wools produce a moderate amount, and short staple wools like Merino produce more because more fiber falls below the transfer threshold
• Noil is not waste — it contains real wool fiber with different properties than combed top, suited to woolen spinning, blending, felting, stuffing, and textured yarn rather than smooth worsted spinning
• Noil from different breeds behaves differently — longwool noil is relatively long and lustrous; fine wool noil is shorter, finer, and felts easily; the source breed shapes the character of the noil just as it shapes the combed top
• Carding noil before spinning opens the fiber, removes remaining debris, and creates a more organized preparation that drafts more easily — it also makes blending with other fibers much more effective
• Store noil separately from combed top in a labeled container — keep it dry and away from pests, and accumulate enough from multiple sessions before using it for blending or woolen spinning projects
• A productive combing session yields two things: smooth combed top for worsted spinning and noil for its own set of projects — saving both is the full return on the time and fiber invested in combing

Frequently Asked Questions

What is noil in wool combing?

Noil is the collection of short fibers that remain behind on the combs after the longer fibers have transferred away during combing. It consists of shorter staple fibers, second cuts from shearing, small bits of vegetable matter, and any fiber that is too short to align cleanly with the combed top. Noil is a natural byproduct of combing — the more thoroughly the combs separate long fibers from short ones, the more defined the noil pile becomes. The amount and character of the noil depends heavily on the fiber being combed and the staple length of the fleece.

Can noil be spun into yarn?

Yes — noil can be spun into yarn, though it behaves very differently from combed top. Because the fibers are short and randomly oriented rather than aligned in parallel, noil produces a woolen-style yarn that is soft, airy, and lofty rather than smooth and strong. Some spinners card the noil first to open and organize it before spinning, which makes drafting easier. Others spin it directly for a more textured, rustic result. Noil yarn is not suited to fine or smooth spinning, but it can be charming for projects where a softer, more casual texture is desirable.

Why does combing produce noil?

Combing produces noil because the process is specifically designed to separate fibers by length. As the fiber transfers between combs, the tines catch and move the longer fibers while the shorter ones — those that don't have enough length to grip and transfer cleanly — remain behind. This selective separation is what gives combed top its smooth, parallel structure and makes it draft so cleanly during spinning. Noil is the inevitable result of that selection process: the fibers that were too short to make the cut. A higher noil yield simply means the combs did a thorough job of separating long from short.

Is noil waste fiber?

No — noil is not waste, even though it can't be used for smooth worsted spinning. It still contains real wool fiber that can be put to good use in a variety of ways. Many spinners save noil for woolen spinning, fiber blending, felting, or stuffing handmade crafts. Silk noil — the short fiber byproduct of silk processing — is actually sold commercially as a desirable blending fiber, which gives a sense of how valuable short fiber byproducts can be. Wool noil deserves the same respect: it's a different material with different properties, not a failure of the combing process.

How much noil is normal when combing wool?

The amount varies considerably depending on the fiber. Long wool breeds like Lincoln and Leicester Longwool typically produce very little noil because most of the fiber is long enough to transfer cleanly. Medium staple wools like Corriedale produce a moderate amount. Short staple wools like Merino produce more noil because a larger proportion of the fiber falls below the transfer threshold. Fleece with many second cuts — very short fibers from a second pass of the shears — will also produce more noil. If you're producing what feels like an unusually large amount of noil, short staple length or second cuts are usually the cause.

How should noil be stored?

Store noil separately from your combed top in a paper bag, cloth bag, or lidded container. Label with the fiber type if working with multiple breeds. Accumulate noil from multiple sessions before using it for blending or woolen spinning. Keep it dry and away from pests.

Does noil from different wool breeds behave differently?

Yes, noticeably. Noil from long wool breeds like Lincoln or Wensleydale tends to be relatively long for noil — the short fibers from a long-staple fleece are still longer than the short fibers from a fine-wool fleece — and it often has a lustrous, silky quality that makes it pleasant to spin or blend. Noil from fine wool breeds like Merino is much shorter and finer, producing a softer, fluffier noil that felts easily and blends well with other fine fibers. Noil from medium wools falls somewhere in between. The breed of the source fleece shapes the character of the noil just as much as it shapes the character of the combed top.

Can I card noil to prepare it for spinning?

Yes — carding noil before spinning is a common and effective approach. Because noil fibers are short and randomly oriented, running them through hand cards opens the fiber, removes any remaining debris, and creates a more organized preparation that drafts more easily than raw noil. The result is a rolag or batt of short fiber that spins into a soft, woolen-style yarn. Carding also makes it easier to blend noil with other fibers — adding a small amount of silk, alpaca, or longer wool to the noil during carding can improve the drafting quality and add interesting texture or sheen to the finished yarn.
