What is PatternLab?

PatternLab is a new flat pattern-making tool, developed specifically for creating made-to-measure basic sewing patterns* for garments that fit like a glove. PatternLab dramatically speeds up the production time of your garment or collection, giving you more time to focus on what really matters, the design process!

* Basic sewing patterns can also be referred to as basic blocks, basic sewing pattern blocks, slopers or sewing blocks.

“We automatically draft basic sewing patterns in minutes, saving you hours.”

We have spent years deconstructing, studying, and experimenting with a variety of different pattern-making techniques- techniques that are either outdated or far too standardised. Our response was to create a simple, reliable process to draft basic sewing patterns that fit accurately on a range of sizes and body types. Each basic sewing pattern we create takes us years of painstaking analysis and reverse engineering until we find the method that works.

Our formulated method automatically drafts a unique basic block for each customer, based on their individual measurements. PatternLab does not transform, scale or grade from existing basic sewing patterns. Instead. we automatically draft each basic block from scratch, point-to-point and measurement by measurement, to get a unique fit each and every time. Each basic block we draft is unique to its wearer, which ensures only an absolute minimum number of fittings and adjustments is required.

What you get?

We sell our basic sewing patterns in two formats to suit the various needs of our customers. It is entirely up to you what format you purchase patterns in and how you use them.

PDF Paper patterns

For those that prefer manual or hand-drawn patterns, we provide full-scale, multi-page, PDFs in a range of common paper sizes including US Letter, A4, A3, A2, A1 and A0.

Editable digital ePatterns

An ePattern is a full-scale editable version of your basic sewing pattern, saved in the form of an SVG file (Scalable Vector Graphics). ePatterns give you the ability to edit or re-draw the lines of your drafted blocks. They work in conjunction with our online courses and tutorials. An ePattern can be imported or opened in a variety of different software applications that accept the SVG format such as Adobe Illustrator and Inkscape, to name but a few.

Who is it for?

Our software is designed for both novices and professionals alike. Our customers come from a variety of disciplines and include self-taught creators, students, graduates, designers, pattern-makers, seamstresses, hobbyists and more! PatternLab customers often comment on how simple and effortless the process is and many have spent years trying to find a block that works for them or their clients. We help them save time and money, and lots of it!
