Fibre choice sets the ceiling for what a cloth can become. The same draft in wool, linen, or cotton produces three different fabrics, because each fibre brings its own elasticity, moisture behaviour, and surface. This article compares the four natural fibres a handweaver reaches for most, and notes how each behaves through a Canadian year, where heated winters are dry and many summers are humid.
The four workhorses
Below is a working comparison. Treat it as orientation rather than a rulebook — within each fibre, preparation and grist change the hand considerably.
| Fibre | Character on the loom | Best suited to |
|---|---|---|
| Wool | Elastic, forgiving, blooms when wet-finished | Scarves, blankets, garments |
| Linen (flax) | Inelastic, strong, needs steady tension | Towels, table linens, crisp cloth |
| Cotton | Soft, stable, easy to handle | Towels, everyday yardage |
| Hemp | Very strong, stiff at first, softens with use | Bags, sturdy household cloth |
Wool: the forgiving start
Wool's natural crimp gives it elasticity, which hides small inconsistencies in beat and tension — part of why it suits new weavers. It also fulls and blooms during wet finishing, closing up the cloth and softening the hand. The trade-off is that an over-fulled wool can felt and shrink markedly, so finish a sample first and note how much it changes.
Canadian seasonal note
In a dry, heated winter, wool warps can build static and cling. A cooler, slightly more humid workspace calms this; some weavers simply weave wool in the more humid parts of the year and save crisp linen work for drier spells.
Linen: strength without stretch
Flax fibre is strong but has almost no elasticity, so a linen warp is unforgiving of uneven tension and likes a firm, consistent beam. Worked well, it produces cool, durable cloth with a characteristic crispness that improves with washing. Linen is sensitive to dry air, which can leave it brittle; many weavers prefer to dress a linen warp when the room is not bone-dry.
Cotton: the dependable middle
Cotton sits between wool and linen in handling — more stable than wool, more elastic than linen. It is widely available in many grists and takes dye readily, which makes it a sensible choice for first towels and for testing a new structure before committing pricier yarn. Mercerised cotton adds sheen and strength if you want a more refined surface.
Hemp: rugged and long-wearing
Hemp resembles linen in being strong and inelastic, but tends to feel stiffer off the loom. With washing and use it softens noticeably, which suits bags, mats, and household textiles meant to last. Because it resists abrasion well, it is a good warp where durability matters more than initial softness.
Matching fibre to project
Name the end use
A towel wants absorbency and stability; a shawl wants drape. The use narrows the fibre before anything else.
Check your skill against the fibre
If even tension is still a struggle, wool or cotton forgives more than linen or hemp.
Sample and finish it
Wet-finish the sample exactly as you will the cloth, because the loom state and the finished state can look like two different fabrics.
