Tablet weaving makes narrow, strong, gloriously patterned bands with nothing but pierced cards, thread, and a loom to hold tension. The pattern does not live only in the threading — it lives in the turns: each card rotates between picks, and which threads ride on top decides the color of the band. Change the turning sequence and the same threading weaves a different band. It is the closest thing stringcraft has to programming, and it's been worked since at least the Iron Age.
| Item | What to get | Notes |
|---|---|---|
| Tablets (cards) | 8–20 four-hole cards; sturdy cardboard or thin plastic works | Corner-hole cards are the classic; big-box playing-card stock is a fine student material |
| Thread | Cotton crochet/pearle 3/2 or 5/2 | Warp-faced: the warp thread carries all the color, so the warp is your palette |
| Loom | Any tension device: an inkle loom, two roller bar, or C-clamps at a table | The app's preview works at 1:1 on any band loom |
| Shuttle | A flat stick shuttle with a notch | The weft is mostly hidden — plain ugly weft, plain fine |
Each card's four holes take four warp threads. The card has a right side and a back side; threading all four from the front-left hole across gives one twist direction, threading right-left gives the other — written as S and Z. Why it matters: S-threaded and Z-threaded cards lean their twill lines in mirror image, so the band's diagonals point one way or split into diamonds. A "double-face" first warp uses two dark and two light threads per card — for the classic setup, all the same orientation, darks and lights in the same hole positions per card.
Thread every card two dark, two light, all the same direction. Weave a pick with the cards in their starting positions; then turn all the cards a quarter turn in the same direction, weave a pick; turn again; weave. That's it. The band will stripe and shimmer as the two faces trade places — dark surface, then light, and with a little patience, figures, because the direction each card turns is yours to choose, card by card: F (forward), B (back), or held still.
A pick order like F F F B — three forward, one back — writes an arrow into the cloth. Repeating F B per card-pair gives chevrons; holding some cards still while others turn writes blocks. The chart in Fiber Bench shows both things at once: the draft (how the cards are threaded) and the sequence (which way they turn on every pick, for every card). Read it the way you'd read drum tablature — one line per card, one step per pick.
Every turn twists the warp threads around each other. A band woven all-forwards forever slowly ratchets a twist into itself until the shed fights back. Two honest cures:
| Symptom | Cause | Fix |
|---|---|---|
| Band narrows as it goes | Weft tension beating the warp down | Weft should arc generously, then beat to snug — never beat to crush |
| Pattern comes out split backwards | An S card among the Zs (or the reverse) | Follow the draft's S/Z column exactly; one card off shows up forever |
| Shed refuses to open after a few picks | Twist ratcheted too far | Insert the twist fix above — reverse the sequence's direction; don't just force the shed |
| Edges look frizzed | Warp threads sliding off card holes | Keep every thread seated in its hole — re-seat, don't re-warp |
One warning worth keeping: card weaving hooks hard. The first successful figure on your band is the moment it stops being a craft project and becomes a vocabulary.
The Studio's tablet simulator turns the cards in front of you — plain, diamonds, chevrons — so you'll recognize the pattern in the app's preview before you warp.
