How to read a formula
A segment like 20a means twenty threads using color key a. A full formula chains segments together, such as 20a2b20a2c.
Formula guide
Textile formula guide for warp and weft patterns
TextileWeave formulas are compact pattern instructions. A number defines how many threads to draw, and the following letter defines the thread color key. Repeating those segments creates fabric structures.

Warp versus weft
The warp formula controls the vertical thread sequence. The weft formula controls the horizontal thread sequence.
Matching and contrasting repeats
Use the same formula in both directions for balanced checks, or different formulas for stripes, plaids, and asymmetric layouts.
Workflow
From idea to exportable pattern.
01
Start with two colors
Write a short repeat using color keys a and b.
02
Add accent lines
Insert short segments such as 2c or 1d to add contrast.
03
Preview and refine
Change counts, density, and colors until the visual weight is correct.

Can formulas include multiple colors? +
Yes. Use any available color key in the formula, such as a, b, c, d, e, f, and beyond.
