String is the quiet giant of technology. Bows, nets, snares, fishing lines, lashings, tethers, slings, baskets, sails, belts, and every pre-modern machine transmission depend on twisted fiber. A civilization without cordage cannot hunt efficiently, build flexibly, or transmit power.

3.1 Fiber Selection

Harvest bast by stripping bark ribbons and retting (soaking until soft tissue rots loose), then scraping. Flax dew-rets in grass fields for weeks; water-retting is faster but smellier.

Retting SOP: bundle ribbons, submerge (pond) 5–10 days or spread (dew) 2–4 weeks; test daily — fiber slips free from bark when done, mush when overdone. Rinse, dry, break over a knee (shive falls), scutch + hetchel (comb through nails) to clean long line fiber from tow. Line spins fine thread; tow twists coarse cord and caulking.

3.2 Twisted Cordage: Reverse Wrap

Two-ply reverse wrap is the universal method: twist one strand tightly clockwise while folding it over the other counter-clockwise; the opposing torsion locks each half-twist. Key rules:

• Twist tightness = strength. Under-twisted cord fails at knots.
• Ply against fiber's natural twist for balance.
• Splice in new fiber with staggered tails so no point carries all the load.

Key threshold: a properly made 3 mm two-ply cord of bast fiber holds 20–50 kg. Multiply strands: doubled diameter ≈ quadruple strength. This arithmetic turns hand-made cord into rigging capable of hauling logs, well-buckets, and later millstones (Ch 16).

Rope-making scales up with a simple rope walk: three or four cords paid out between two posts, wound together on a top with a crank, counter-tension (a weighted sledge) at the far end. A ship's hawser needs a long walk — historical rope walks ran a few hundred metres — and a practised crew.

FIBER → ret → scutch/hetchel → REVERSE-WRAP 2-ply → 3-ply cable-laid
   → ROPE WALK (3–4 cables + top + crank) → HAWSER (tarred for weather)

Cordage grades (stock all three): thread (<1 mm, sewing/nets), cord (2–4 mm, snares/bowstrings/lashings), rope (8 mm+, hauling/rigging/mill drives). Wax thread with beeswax/pitch for sewing; tar rope for weather; keep sinew dry (strength collapses wet, returns dry).

Knots worth drilling — cordage is only as useful as the knots that fasten it. Teach each until it can be tied blind and checked by eye:

Most knots cut a rope's breaking strength by roughly a fifth to a half at the knot, depending on knot and fibre. Rate any rope that lifts loads or people with that loss included, and never use improvised cordage to support a person.

3.3 Basketry and Containers

Three weave families cover all needs:

• Coiling (sewn spirals): strong, watertight-capable with tight stitching; ideal for grain storage and hot-stone cooking baskets.
• Twining (active warps twisting around passive wefts): flexible, strong bags, fish traps, snowshoe frames.
• Plaiting (checkerboard over-under): fast mats, screens, basket bases.

Waterproofing options: pine-pitch linings, clay-plastered interiors (a stepping stone to pottery — some ceramic traditions began as fired baskets), or tightly coiled grass and root baskets that swell shut when soaked.

Hot-stone cooking (basket cuisine): watertight coiled basket + heated stones from the fire (Ch 1) → stones cycle fire-to-basket, water boils without a pot. Grains, stews, and fish oils all predate ceramics this way — the Jōmon lipid record (Ch 5) has a basketry prequel.

3.4 Hides: From Skin to Leather

Raw hide rots and stiffens unpredictably; processed leather does neither. Two main routes:

1. Brain tanning (buckskin): scrape membranes from a dehaired hide, work an emulsified brain-water mash (lecithin does the work; every animal has enough for its own hide) into the fibers, wring, smoke over rotten-wood smudge. Result: soft, washable buckskin.
2. Vegetable tanning: soak dehaired hides in progressively stronger baths of oak/birch bark liquor (tannins cross-link collagen) for weeks to months. Stiffer, firmer leather — the stuff of soles, buckets, belting, and later machinery drive-belts (Ch 16).

Either way: flesh, dehair (a wood-ash lye or slaked-lime soak loosens hair; both burn skin and eyes, so handle with gloves and rinse spills at once), frame-stretch, and dry evenly. Hair-on hides make winter robes; rawhide makes glue stock and drum heads.

Dead end avoided: treating the hide as a by-product of the meat. An untanned skin starts to rot within a day or two in warm weather, so a hunt or slaughter without a hide plan wastes the animal's second most valuable yield. Flesh, salt or dry, and frame the hide the same day as butchery.

3.5 Woven Textiles

The loom separates threads into tension-bearing warp and interlaced weft:

• Warp-weighted loom: upright warp threads hung from a bar, tensioned by clay loomweights — buildable with pottery from Ch 5.
• Weaving beats knotted-netting for cloth density; tablet weaving produces strong decorative bands for straps and trim.
• Wool arrives with domesticated sheep (Ch 8); linen from retted flax; cotton where climate allows. Spinning (drop spindle: weighted stick twisting fiber into continuous yarn) is the bottleneck labor — one spinner supports roughly one weaver.
• Dyeing: plant dyes (woad and indigo for blue, madder for red, weld for yellow) colour cloth, but most need a mordant — a metal salt, above all alum (Ch 17 §17.2), that binds dye to fibre; iron salts dull and darken shades. Indigo is a vat dye: reduced in an alkaline bath to a soluble form, it turns blue on the fibre as air re-oxidises it. Some mordants (copper, chrome) and dye plants are toxic, so dye pots and food pots never trade places.

Jump: once you understand spinning and weaving, skip millennia of incremental loom evolution and go straight to a treadle-driven horizontal loom with a heddle frame — foot-powered shed-changing multiplies output several-fold and anticipates mechanized weaving. Do the same on the spinning side, where the real bottleneck sits: a driven spinning wheel (foot treadle turning the spindle) multiplies one spinner's thread output roughly threefold over a drop spindle, and Hargreaves' jenny (1764) — eight spindles per operator, later far more — is the documented proof that parallelizing spinning was the century's payoff before power machinery took over (Ch 23).

3.6 Why This Chapter Gates Everything

Nets raise fishing yield per calorie spent by an order of magnitude (Ch 4). Bowstrings enable the most efficient handheld weapon below gunpowder. Lashings hold shelters and boats together. Belts transmit rotary power. Sewn clothing lets humans colonize arctic latitudes. Treat fiber technology as infrastructure, not craft: stockpile it like grain.

3.7 The Material Record

Textiles and cordage preserve badly, so each survivor carries weight:

• Dzudzuana Cave, Georgia: dyed wild flax fibers dated ~34–30 ka — the oldest known colored textile fibers.
• Eyed needles appear by ~40–50 ka; a bird-bone specimen from Denisova Cave (~50 ka) is the oldest yet found — sewing fitted clothing enabled cold-climate occupation.
• Venus figurines (Gravettian) repeatedly depict woven or corded garment textures — indirect but repeated evidence that fiber clothing was normal by ~28–22 ka.
• Ötzi the Iceman (5,300 BP) traveled alpine passes with a full fiber kit: stitched hide-and-leather clothing, grass-net cape, cordage, unfinished yew bow, copper axe hafted with leather and tar — a complete snapshot of Chalcolithic fiber craft.
• Spindle whorls and loom weights appear in Neolithic strata wherever textiles scale up; warp-weighted looms dominate early European house plans.
• Silk sericulture carries legendary dating to ~2700 BCE (Empress Leizu tradition); archaeological silk finds run earlier and remain debated. Cotton threads appear at Mehrgarh by ~5000 BCE; wool follows sheep's fleece transformation (wild sheep have hair, not wool — fleeced breeds are themselves a product of Ch 8-style selection).

Historian's caution: absence-of-evidence dominates this field — most string ever made rotted. Perishables' history is reconstructed from lucky microclimates (caves, waterlogged bogs, ice), and every generalization should carry that caveat.

3.8 Cloth Math and Care

Thread count per cm × loom width = warp ends to spin (a 60 cm cloth at 10/cm needs 600 ends — spin accordingly). Fulled wool (woven cloth pounded wet) shrinks dense and sheds rain; linen must dry fully or it mildews; store cloth with ash or cedar against moths, rolled rather than folded, and never damp. Patch early — a darned elbow outlasts a replaced sleeve.
