More than a PDF download

A free drafting workspace, not a library of fixed-size files

Many pattern pages begin with a finished file and ask you to fit yourself into its size chart. Nastix Patterns works in the other direction: you choose a generator, enter the measurements for your project, and the browser recalculates the draft. The result is a working pattern based on your inputs rather than a picture of a standard size.

Every available generator is free to open and use. The growing collection brings garment foundations and the smaller pieces that often slow a sewing project down into one accessible place—from bodices, skirts, pants, sleeves, and knit tops to collars, cuffs, waistbands, facings, pockets, a hood, and a zipper fly.

Generated for your inputs

The draft changes when your measurements change

The generators use the values you enter to build the pattern geometry. That makes them useful when a fixed ready-made size is not the right starting point or when a detail must match another part of a garment.

Body measurements, finished dimensions, ease, and construction settings remain visible and editable.
Related pieces such as a bodice and sleeve, a neckline and facing, or a cuff and overlap are drafted as a coordinated set.
The on-screen preview lets you catch an unusual proportion or setting before downloading the file.

Free working files

Useful output without a checkout

This is not a preview-only catalogue. You can configure a pattern, generate it, and download a file prepared for the next step in a real sewing project.

More than twenty free generators cover foundation blocks, garments, finishes, closures, and pocket details.
SVG export keeps clean vector paths for technical editing or digital workflows.
Full-size and tiled A4 PDF options support copyshop printing or an ordinary home printer when available for the selected pattern.

Guided starting points

Presets make the first draft approachable

You do not need to know every drafting value before you begin. Presets provide practical combinations for common fits, silhouettes, shapes, and construction methods while leaving the individual controls available.

Start with familiar choices such as fitted, relaxed, A-line, oversized, rounded, pointed, or elastic.
Change any measurement after selecting a preset instead of being locked into a standard size.
Use the preview and measurement guides to see how one adjustment changes the resulting pieces.

From screen to fabric

Files prepared for actual sewing

A pattern becomes valuable when it can leave the screen. The generators label pieces and add the practical information needed to identify, print, cut, and assemble them.

Depending on the generator, output can include grainlines, fold lines, notches, placement marks, cut quantities, and seam allowances.
Tiled pages include assembly references, while printable files provide a scale check so the dimensions can be verified before cutting fabric.
Construction notes and in-depth guides explain what the pieces are for and what to check during sewing.

Built to be useful

A practical resource for learning, experimenting, and everyday sewing

Home sewists

Create a starting pattern without buying a separate file for every small garment detail, then adjust it for the person and project you are sewing for.

Students and teachers

Compare presets, change one value at a time, and use the visible draft to understand how measurements and construction choices affect pattern pieces.

Makers and designers

Build quick prototypes, export editable vectors, and generate supporting pieces without redrawing the same collar, cuff, pocket, or closure from scratch.

Free does not mean skipping the fitting check

Measurements, posture, fabric behaviour, printer settings, and sewing technique all affect the finished garment. Print at 100%, verify the scale marker, compare critical seams, and sew a toile or test piece before cutting valuable fabric. Nastix Patterns gives you a calculated starting point and practical tools; the final fit still deserves a real-world check.

Why it works

Why Nastix Patterns

A focused drafting workflow for makers who need clear pattern blocks, printable files, and practical construction details without opening a heavy CAD tool.

Measurement-led drafting

Each block starts from the values that matter for the garment: body measurements, ease, opening lengths, allowances, and construction choices. The preview keeps those decisions visible before export.

Files prepared for real use

Export clean SVG for editing, copyshop PDF for full-size output, or A4 tiled PDF for home printing. Test squares and clear line styles help keep scale and construction readable.

Built around sewing details

The library combines core blocks with practical parts like vents, cuffs, waistbands, belt loops, pockets, and flaps, so a project can move from base shape to finish details in one place.
