Choosing raw or washed wool fiber is partly a choice about where you want your spinning project to begin. Raw fleece gives you responsibility for sorting and cleaning. Washed fleece removes much of that work, but it may still need opening, carding or combing before you can comfortably draft it into yarn.
The useful question is not simply which costs less per pound. Ask what condition the wool is in, how much usable fiber you will receive, and which preparation steps you have the time, space and tools to do.
Editorial note: This is a modern educational guide about sheep’s wool. It is not a recreation of the former Homestead Wool & Gift Farm store, and it does not describe or offer its historical products. The guidance is research-based; no personal fleece-processing or product-testing experience is claimed.
Raw, washed and prepared wool are different starting points
Raw or unwashed wool has not been scoured. It can contain wool grease, dirt and other material acquired before or during shearing. Washed or scoured wool has undergone cleaning. Woolmark describes scouring as washing with detergent, rinsing and drying to remove contaminants including wool wax, dirt and sweat salts.
Prepared spinning fiber has had additional work done to organize the fibers. A bag of washed locks is therefore not the same purchase as combed top. “Cleaned” is worth clarifying with the seller: ask whether it means washed only, picked open, carded, or combed.
| Starting material | What to establish before buying | Work to plan for |
|---|---|---|
| Raw fleece | Skirting, grease, debris and overall condition | Further sorting, a cleaning plan, drying and fiber preparation |
| Washed loose wool or locks | Residual grease, debris, tangling and lock integrity | Inspection and appropriate opening, flicking, carding or combing |
| Carded or combed wool | Exact preparation, fiber content and suitability for your intended yarn | A small drafting and spinning sample before committing the batch |
These are buying checkpoints, not guarantees attached to a label. Neither “raw” nor “washed” is a quality grade.
Which should you choose?
Choose raw fleece when preparation is part of the project
Raw fleece can make sense if you want to learn about the material from the beginning and can examine a representative sample. Before buying a whole fleece, identify where you will sort it, how you will wash manageable batches and where they can dry completely. Include the cleaning supplies and preparation tools in your budget.
A small sample is a more manageable first commitment than an unfamiliar whole fleece. Use it to find out whether the work interests you and whether the fiber suits your intended yarn. A low purchase price is less attractive if you discover that much of the material is unsuitable for your project.
Choose washed fleece when you want to prepare fiber without doing the wash
Washed wool is a useful middle ground if your interest is in opening locks, carding or combing. Ask for photographs that show the fiber spread out as well as in the bag. Find out whether the weight quoted is the dry washed weight and whether any additional sorting is expected.
If your immediate goal is to practise drafting and controlling twist, consider an already prepared fiber rather than assuming washed fleece will be ready to spin straight from the bag. Buying yarn instead is another starting point entirely; our wool yarn guide explains how to choose the finished spun material.
Inspect the fleece before comparing prices
The Joy of Handspinning’s fleece-selection guidance highlights short second cuts, debris, stains and older hardened grease as things to examine. Washing is not a substitute for selecting suitable fiber in the first place.
- Ask what was removed. Skirting sorts out unwanted portions of a fleece; it does not mean that every seed or piece of hay has disappeared.
- Look beyond one attractive lock. Request a representative sample and ask about variation across the batch.
- Check length and condition. Ask for the staple-length range and whether the seller has noticed weak or brittle sections. Choose with your preparation tools and intended yarn in mind.
- Clarify remaining work. For washed wool, ask about residual grease, vegetable matter and compacted or matted areas.
- Confirm identity. Establish the breed or blend if known, whether the lot mixes fleeces, and whether it has been dyed or otherwise treated. An unknown detail should stay unknown.
Keep the seller’s description with the batch. It gives you something specific to compare with the material that arrives and helps prevent mixing up samples.
Compare usable fiber, not just bag weight
Raw weight includes material that cleaning and sorting may remove. Further preparation can also separate out fiber you will not use in the main yarn. There is no single yield percentage that should be assumed for every fleece.
For a hypothetical example, suppose 1 kilogram of raw fleece costs $24 and your own sample suggests a 60% usable yield through your planned preparation. That would mean an estimated 600 grams usable, or $4 per 100 grams before washing supplies, tools, shipping and your time. The 60% is an example for arithmetic, not a typical yield claim.
Compare that result with the same endpoint for washed fiber. Washed loose wool may still lose material during preparation, so its sale weight is not automatically the weight of finished yarn. A sample-based estimate is useful; a supplier’s unexplained percentage needs clarification.
Plan cleaning before spinning raw wool
Scouring raw fleece is a fiber-processing job, not the same task as laundering a finished wool garment. Follow a method and detergent intended for raw wool, and begin with a small batch. Unicorn Clean’s raw-fiber instructions, for example, specify product-dependent water temperature, dilution and soaking, with rinse water at the same temperature. Those directions should not be treated as a universal recipe for every detergent.
Prepare the bath before adding fiber, allow enough room for it, and avoid kneading or excessive movement in the water. The Joy of Handspinning also advises against directing running water onto the fleece and stresses gentle handling to limit felting. Arrange a drying space before starting, and let the washed fiber dry fully before storing it.
Some handspinners work “in the grease,” spinning unwashed wool and cleaning the yarn later. That is a deliberate technique, not proof that any dirty fleece is ready for your equipment. Check your tool manufacturer’s instructions before putting unwashed material through cards or other equipment.
What comes after washing?
Cleaning and organizing the fibers are separate operations. In its explanation of top-making, Woolmark describes further disentangling, alignment and removal of short fibers and remaining contaminants after scouring. At a handspinning scale, choose the preparation to suit the fiber and the yarn you want.
- Working with individual locks: Keep lock structure in mind if you intend to open the ends and work from locks.
- Carding: Consider a carded preparation when you want a blended, airy fiber supply. Match the tool and handling to the wool rather than forcing an overloaded batch through.
- Combing: Consider a combed preparation when you want greater alignment and separation of shorter fibers. Allow for the material removed during preparation.
The Joy of Handspinning’s preparation overview distinguishes common forms such as locks, rolags and combed top. Retail terms can vary, so ask what was actually done rather than relying on a name alone.
Prepare and spin a small sample before processing everything. Record whether it drafts comfortably, what you removed, and whether the resulting yarn suits the project after finishing. Our handspun wool yarn guide helps connect yarn variation and sampling with project planning.
A short decision checklist
- Do you want to learn fleece processing, or start spinning sooner?
- Do you know the batch’s condition and the exact preparation already completed?
- Have you compared costs at a similar usable-fiber stage?
- Do you have appropriate tools and a workable washing and drying space if needed?
- Can you try a representative sample before committing to the whole batch?
Choose raw fleece when the preparation is work you want to do. Choose washed fleece when you want to begin further along, and prepared fiber when organizing loose wool is not part of your current project. The right purchase is the one whose remaining work you understand.
