# A colourwork chart is a pixel grid that predates pixels

> Knitting charts encode a pattern as a grid of filled squares with a stitch key beside it. Printed at chest size, it is both a strong geometric graphic and a set of instructions.

A grid of filled and empty squares forming an eight-pointed star, rows numbered up the side, and a
key down the left listing what each symbol means.

It's a set of instructions. It's also, without changing a thing, a geometric print.

## Why does a knitting chart work as a graphic?

Because it was already a grid of high-contrast squares.

Charts have to be readable at arm's length by somebody counting under lamplight, which forces the
same qualities a fabric print needs: hard edges, flat fill, strong repeat, no gradients. The
constraint that made it a good instruction sheet makes it a good print.

It also sits in a long tradition. Grid-based ornament predates knitting charts by centuries and
predates screens by rather more —
[which is why pixel work still reads as ancient and modern at once](/stories/retro-pixel-art-tee).

## What should the chart show?

Something they actually knitted.

A motif from a finished yoke, a section of a colourwork band, the repeat from a pair of gloves that
took a winter. Charting a project they completed turns the shirt into a record rather than a
pattern library.

The row numbers matter more than they look. They give the design an axis and they're the detail
that tells another knitter this is a real chart rather than decoration shaped like one.

## Can it use a published pattern?

A designer's chart is their work, so a reproduction of one isn't available for merchandise.

Knitting patterns are written and drawn documents, and independent designers make their living from
them — this is a community that takes attribution seriously and notices quickly. The stitch symbols
themselves are shared notation, in the way musical notation is shared, but a particular motif
arranged by a particular designer isn't.

Their own chart, a traditional motif, or a fresh one drawn on the grid all avoid the question. And
traditional geometric motifs are a deep, old, unowned vocabulary.

## Does it work for other fibre crafts?

Each has its own document, and they're all grids or diagrams.

Cross stitch shares the chart form outright. Weaving has a draft — threading, tie-up and treadling,
which is a strikingly graphic four-block layout. Crochet has symbol diagrams that radiate from a
centre and look like nothing else. Quilting has block construction drawings.

A weaving draft in particular is one of the more beautiful technical documents in any craft, and
almost nobody outside weaving has seen one.

## Is it a gift or something for a maker to sell?

Both work, and the maker version has an angle.

Somebody who designs patterns can print their own chart as merchandise that only they can sell,
which is a rare position to be in. For a gift, the appeal is that it's specific to one project one
person made.

For a group — a knitting night, a guild — the same motif on different garment colours reads as
[a set rather than a uniform](/stories/family-reunion-shirts).

## What about the stitch key?

It's the part that makes it look like an instrument.

A column of small symbols with their meanings beside them adds a second texture and a strong
vertical edge, and it's genuinely informative to a knitter. It should carry fewer entries than a
real key — six or eight — set larger than a pattern would print them.

## Does it print well?

Unusually well — it's flat squares on a grid.

Hard-edged blocks with even spacing are close to the friendliest possible artwork for fabric. The
one thing to watch is grid density: a chart at true pattern scale can run sixty stitches wide, and
sixty columns across a chest reduces each square to a speck. Around twenty-four to thirty columns
keeps the individual stitches legible.

Lilac, oatmeal, heather and moss read as yarn colours. Two inks is plenty and one often looks
better.

## How do I get one made?

Describe the chart at [JustOG](/) — the motif, the grid size, and what the key should list. Pick a
direction, drag the crop frame, see it composited on the real garment, and it's made to order and
shipped.

Designs other people have published are in the [shop](/shop).

Somebody counted every one of those squares.
