Herringbone stitch — also called Ndebele stitch — grows in columns of bead pairs that lean together like a V, which is where the name comes from: the chevron look of herringbone tweed, or a fish's spine read backwards. Where square stitch lays beads flat in counted rows of single beads, herringbone stands beads on end in straight columns and leans them in pairs, and that lean is the entire personality of the fabric.
Each stitch adds two beads that sit on two beads of the row below, at an angle to each other — Fire Mountain Gems' herringbone page describes how the two-bead stitch makes the beads angle up row by row. No source checked says which way the angle has to point; the fabric just does what its column tells it. That's why the app draws each pair leaning apart and lets the look happen.
| Item | What to get | Notes |
|---|---|---|
| The beads | Delicas or round seed beads, size 11/0 | Delicas give neat, even columns; round 11/0s soften the look. The app charts herringbone in size 8/0 and even 15/0 too, but every starter starts you on these |
| Needle | Size 12 beading needle | The tutorials' pick for herringbone — a long, thin needle made for seed beads |
| Thread | Nylon beading thread, such as S-Lon — start with about 1.5 m (5 ft) | A longer thread means fewer joins; you can add more later |
| Clasp | One, for a flat bracelet | Closing a herringbone band is a weave-in and knot job — the same pass both ends back, knot between beads, trim finish every thread craft here shares; the clasp is the app's only listed finding |
| Extras | Scissors | That's the list. No loom, no frame — a ladder and a thread |
Herringbone only works on an even count across: the ladder that starts it is an even-count ladder, and every stitch takes two beads off two of its rungs. An odd width strands half a pair at the end of every row. Fire Mountain Gems' and PotomacBeads' flat tutorials both start on even ladders, and the app doesn't even offer you the wrong choice — its size sheet steps herringbone in twos, from 4 to 40 beads across.
The app's starter pieces follow, with the repeats its size sheet works out from a 7 in target (whole repeats, so the finished lengths land just over 7 in):
| Starter | Beads across | Stitches a row | Pattern rows | Repeats the app picks | Rows all told | About |
|---|---|---|---|---|---|---|
| Bracelet | 8 Delicas | 4 | 20 | 7 | 140 | 7.2 in long, 12.8 mm wide |
| Narrow band | 4 size 11s | 2 | 12 | 11 | 132 | 7.3 in long, 8.4 mm wide |
| Wide cuff | 16 Delicas | 8 | 24 | 6 | 144 | 7.4 in long, 25.6 mm wide |
Where those sizes come from: herringbone beads stand on end, so each column of pairs takes the bead's diameter across (1.6 mm for a Delica) and each row climbs the bead's length (1.3 mm). That's the app's own estimate from the published bead sizes — no published gauge exists for herringbone, so on the screen the sizes carry their "about" flags. The narrow band uses round 11/0s at 2.1 mm across, which is why four of them are still only 8.4 mm wide — columns of small beads, standing nearly vertical.
| Symptom | The real cause | Fix |
|---|---|---|
| The edge of a row pulls loose when touched | The turn went straight back up the bead it came down through — it caught nothing | Turn round the outside of the edge bead and up through the bead you added; or loop under the thread beside it (the Interweave turnaround). Both catch something |
| The columns lurch or wander from the first rows on | The ladder's holes weren't upright, so the columns started leaning before the pairs did | Keep the ladder's holes upright (the app's first tip); if it's built, re-ladder before stitching pairs onto it |
| The row runs out of beads with half a stitch hanging | An odd count across — every stitch needs exactly two beads below | Keep the count even. The app only offers widths in twos from 4 beads across, for exactly this reason |
| A hole in the middle of a row | A place was skipped — each stitch puts two beads on two beads below | Fill the gaps on the chart in Design before you start (the app's Make steps flag them), then rework the row |
| The ladder is stiff, bumpy or zigzaggy | The figure eight wasn't closed each time | Re-ladder: string the next bead, back through the bead before it, then through the new bead again — every rung |
| The piece is shorter than the same chart in square stitch would be | That's herringbone working as designed: rows climb the bead's length (1.3 mm for a Delica), not its diameter | Trust the app's size math, which already counts herringbone's pitch by bead length — and expect pairs of 11/0s to climb a bit more |
Plain arithmetic on the app's own starter counts, with the shopping list's 10% spare (advanced mode offers 0, 10 or 20%), the per-gram figures — Delicas at 200 beads to the gram, size 11s at 110 — and the shop's real tube sizes (7.2 g Delica tubes, 8.5 g Miyuki 11/0s):
| Starter | Beads in the chart | With the 10% spare | Grams | Buy |
|---|---|---|---|---|
| Bracelet (8 × 140) | 1,120 | 1,232 | 6.2 g | 1 tube of 7.2 g |
| Narrow band (4 × 132) | 528 | 581 | 5.3 g | 1 tube of 8.5 g |
| Wide cuff (16 × 144) | 2,304 | 2,535 | 12.7 g | 2 tubes of 7.2 g |
Thread, on the same arithmetic: the app estimates the bracelet at about 5 m (5.4 yd) — the thread passes through each bead about twice, plus 60 cm to finish. It's labelled a rough estimate on the Supplies screen. For the same chart square stitch asks for more, because square stitch re-passes each bead several times.
Shopping notes worth taking to the store: galvanized finishes can rub off with wear and dyed colors can fade in sun or water — Duracoat and PermaFinish are made to last — and the shopping list flags a line when it sees either. The shopping-list builder runs this math in the browser: beads across × rows with the spare, grams and tubes per line. In the app, the Supplies tab works it straight off your herringbone chart, repeats included.
And what the method doesn't cover, honestly: tubular herringbone — the rope-shaped version with a step up each round — is a different structure, and the app charts flat herringbone only. If a tube is where you're headed, learn the flat turn here first; the ladder and the pairs carry straight over to it.
The peyote guide is the app's beginner weave for the same thread-and-grid instincts, and the chart-reading guide teaches the row-by-row read every charted craft here shares. For the words you just met — ladder, Ndebele, tail, tension — the glossary has them drawn out.
