Seed Stitch: Repeat, Multiple and How to Work It
Seed stitch alternates knit and purl within every row, not in columns the way rib does — the result is a small, evenly textured, bumpy fabric that lies completely flat, closer in behavior to garter stitch than to the ribbing it superficially resembles at a glance.
The stitch multiple
The repeat behind seed stitch is a multiple of 2, plus 1 stitch — an odd total, unlike most rib patterns, which need an even count. That extra "plus 1" is what lets the pattern alternate correctly both across the row and from row to row; a plain multiple of 2 with no offset would produce vertical rib-like columns instead of true seed texture. Worked example: an 18-inch circumference at 4.25 stitches per inch multiplies out to 77 stitches, which happens to already be odd, so it satisfies the multiple-of-2-plus-1 rule with no rounding needed at all.
How to work it
Flat, over an odd count: Row 1 — *k1, p1; repeat from * to last stitch, k1. Row 2 — work each stitch opposite to how it appears (purl the knits, knit the purls) — this reversal, not "work as it appears," is what distinguishes seed stitch from 1x1 rib, whose Row 2 instruction is the opposite: work every stitch as it appears.
Why it lies flat despite looking rib-like
Because every stitch alternates knit/purl in both directions (across the row and up the fabric), no single column of all-knit or all-purl stitches ever forms — which is exactly the columnar structure that gives 1x1 rib its pull-in, curl-resistant elasticity. Seed stitch's texture comes from the same knit/purl alternation as rib, but distributed in a way that produces a flat, non-stretchy fabric instead, much like garter's ridges achieve flatness through row-by-row alternation rather than column-by-column.
Yarn use
Seed stitch's textured surface costs real yarn over a plain stockinette equivalent. A 90-square-inch swatch worked at 4.25 stitches and 5.5 rows per inch needs 85 yards before allowance in seed stitch — noticeably more than the identical area in plain stockinette at a comparable gauge would need, reflecting the extra yarn the constant knit/purl transitions consume.
Where it's used
Non-curling borders (an alternative to garter or rib when a flatter, less springy edge is wanted), textured sweater panels, and washcloths and dishcloths, where seed's dense, absorbent texture is genuinely functional rather than purely decorative.
Common mistakes with seed stitch
Forgetting the row-2 reversal rule. Working Row 2 "as it appears" (rib's rule) instead of opposite to how it appears (seed's rule) will silently convert the pattern into 1x1 rib after just one row — a subtle mistake that's easy to make if you're used to ribbing.
An even stitch count when an odd one was needed. Double-check against the multiple-of-2-plus-1 requirement specifically, since it's easy to round to a plain even multiple out of habit from other stitch patterns.

FAQ
Is seed stitch the same as moss stitch? In US terminology, yes, they're the same pattern under two names. In some UK/traditional usage, "moss stitch" and "seed stitch" occasionally refer to subtly different alternation patterns — always check a specific pattern's own written instructions rather than assuming the name alone guarantees an identical repeat.
Does seed stitch need a different needle size than stockinette? Not necessarily, though some knitters prefer sizing up slightly, since seed's dense knit/purl alternation can knit up tighter than stockinette at an identical needle size.
