Weighing fibre before colour

Choosing fabric for a family home is really a decision about how a room will age. Natural cloth does not stay still: linen creases, wool blooms, cotton fades, hemp softens. None of that is a fault. But the fibre you choose determines whether those changes read as patina or as decline, and whether the thing you made survives three children, a muddy dog and a south-facing bay window.

Before you fall for a dye colour, ask four questions of the cloth: how does it wear, how does it hang, how does it clean, and how does it age in daylight? Linen, wool, cotton and hemp answer these very differently.

Linen: crisp, cool and quietly tough

Linen is made from flax, and it is strongest when wet — a genuine advantage in a house where things get washed. It resists abrasion better than cotton, pills very little, and is not attractive to clothes moths. It also has natural slubs and a slight irregularity that hides everyday marks far better than a perfectly smooth weave.

Its reputation for creasing is deserved. Lightweight linen rumples; upholstery-weight linen, from around 300 gsm upwards, holds a fold and looks deliberate rather than neglected. Unlined linen curtains will fade and eventually weaken in strong sun, so line them or accept a softer, sun-bleached look. Expect shrinkage on first wash unless the cloth is pre-shrunk — allow five to ten per cent and cut curtains generous.

Wool: resilient, warm and demanding of care

Wool is the only one of the four that springs back. Its crimped fibres bend and recover, so a wool-covered seat keeps its shape where cotton sags. It takes dye deeply, which means naturally dyed wools hold their colour well and fade slowly and evenly rather than going patchy.

Spills tend to sit on the surface long enough to blot. The trade-offs are cost, moths and moisture. Wool is food for clothes moths, so keep it clean, brush it, air it, and use cedar or lavender in storage. In a steamy bathroom it will feel damp, and hot water with agitation will felt it. As heavy curtain fabric it is superb — warm, quiet, excellent at blocking draughts — but it is warm to sit on in a sun-baked room.

Cotton: easy, versatile, and the first to show wear

Cotton is the most forgiving to sew, dye and live with. It is breathable, soft against skin, widely available and comparatively affordable. For bedding, blinds, loose covers and cushions it is hard to beat.

Its weakness is durability under friction. Pure cotton upholstery abrades at arms and seat fronts, and naturally dyed cotton is often the least light-fast of the four, particularly with madder and other root dyes. If you want cotton in a hard-working spot, choose a tight, heavy weave — canvas weight, 300 gsm or more — and consider a linen or hemp blend to carry some of the strain. Loose covers you can wash at 30 degrees are the pragmatic answer.

Hemp: the slow, steady long-termist

Hemp behaves like a coarser linen: it creases hard at first, softens over years, and resists rot, mildew and ultraviolet light better than any of the others. That makes it excellent for kitchens, boot rooms, bathrooms and floor coverings. Natural dyes sit slightly muted on hemp, which suits a quiet, low-contrast interior.

It is slower to drape and can feel stiff for a season or two, but it will outlast most of what surrounds it. A hemp-linen blend is a practical compromise: hemp's strength with linen's softening hand.

Matching the cloth to the room

• Sun: south and west-facing windows punish dye and fibre alike. Line curtains, favour wool or hemp over cotton, and rotate cushions and blinds so fading stays even.
• Traffic: arms, seat fronts and stair runners take the worst of it. Go for tight weaves and heavier weights, or wool and hemp blends that recover their shape.
• Children and pets: removable, washable covers and pre-shrunk cloth. Avoid loose, snagging weaves; a slubby linen hides far more than a flat cotton.
• Damp: hemp and linen cope well, wool does not. Keep wool out of bathrooms and unheated outbuildings.
• Sample first: order a metre, cut a square, rub it, wash it, and leave a piece on the windowsill for a fortnight. It is the cheapest test you will ever run.

Finally, buy more than you need — ten to fifteen per cent extra. Natural dye batches vary, and matching a panel or a seat cover three years later is far easier when the cloth is already in the cupboard.
