woolnumbers a colourwork sweater pattern built from your gauge — the counts checked before you print versions

A colourwork sweater pattern sized to your gauge — with the math checked before you print.

Paste a motif, enter your blocked gauge and measurements — get a written pattern, chart, yarn estimate and printable PDF.

A motif is the small picture you knit into the sweater in a second colour — like the heart already loaded below. Nothing to set up first: just press Generate to watch it work.

Right now we make one thing well: a custom drop-shoulder colourwork pullover — one intarsia motif, knit flat and seamed, front only.

..X..

A tiny 3-row diamond. . is background; X is one contrast colour. Read it bottom-up: Row 1 is the last line ..X.., Row 2 is .XXX., Row 3 is the top ..X... Rows needn't be equal length — a short row is padded with background to match the widest row; choose which side under the chart.

Pasted a chart upside-down? The bottom line is Row 1 — flip it here.

What this doesn't make yet
  • One construction — a bottom-up, flat-knit, seamed drop-shoulder pullover.
  • The colourwork motif goes on the front only, worked as intarsia.
  • One motif per sweater.
  • Flat pieces you seam — not knit in the round.

The proof

✓ counts reconciled cast-on and finished chest reconciled to your gauge and chart

    Estimates include a 12% safety buffer. Buy all skeins of a colour from the same dye lot — lots vary, and switching mid-piece can show. A tiny contrast amount still means buying one full skein (or a mini-skein).

    Live estimate. The full multi-page written pattern, chart and printable PDF are produced by the Wool & Numbers engine when you press Generate.
