Piece your
gear together
The pattern design platform built for makers.
One canvas — from sketch to cut sheet.
Three modes
One canvas
Design panels, assign materials, and prepare for print.
All on the same canvas.
Features
Everything you need
to design your gear
Line types, connections, variables, 3D preview, and print-ready export. All in one place.
Line Types
Mark seams with zigzag, straight stitch, bartack, and zipper lines.
Reference Images
Drag images onto your canvas to trace and align pattern pieces.
Connect Pieces
Link edges between shapes. Connections inherit line style and length.
Reusable Modules
Drag reusable components onto your canvas. Update once, every instance stays in sync.
3D Preview
See how pieces connect and verify your design before cutting fabric.
Parametric Variables
Drive dimensions with variables and formulas. Change one value and the entire pattern updates.
Node Fabric Engine
Build custom materials with a node-based editor. Layer patterns, noise, gradients, and textures to create unique fabrics.
Text & Comments
Pin rich text annotations and comments directly on your canvas.
Hardware & finishing
Style your build with accurate components
Hardware, binding, webbing, and cord. Designed to match real-world gear construction.
Edge Binding
Wrap any seam in binding tape. Toggle per edge and dial in the width.
Cord
Thread elastic or cord through your design. Define the channel path and it renders as a routed cord.
Webbing
Draw straps directly on your pattern. Set width and material, and see them stitched in place.
Hardware
Drag buckles, rings, and sliders onto your canvas. They snap along webbing, cord, and zipper lines automatically.
Tools
Built-in Tools
Everything you need to design, annotate, and prepare patterns for production. No plug-ins needed.

Frequently asked questions
Historically, a piecer was a textile worker who joined threads and kept looms running smoothly. In pattern-making, designs are built from individual pieces that must fit together accurately. Piecer reflects this: a modern tool for planning and organizing pattern pieces.
All core features are free. No credit card, no trial period. Drawing tools, shape construction, modes, PDF/SVG/DXF export, community sharing, and the fabric node editor are all included. A Pro tier may be introduced later for advanced features.
Any gear you can imagine. Backpacks, hip packs, roll-top bags, harnesses, bike bags, apparel, pouches, tents. If it has panels and seams, Piecer can handle it.
Export to SVG, DXF, or tiled PDF. Print mode generates pages across standard paper sizes so you can print 1:1 patterns at home. Each export includes a cover sheet with pattern info, a materials list (BOM) with fabric yardage, webbing lengths, and hardware counts, plus markings like notches, grain lines, and seam allowances.
Your patterns are stored securely in the cloud and are private by default. We never share personal data. Only your public username is visible on patterns you share.
No. Piecer is built to be approachable whether you're sketching your first pattern or have years of experience.
