How Projects Begin

Development projects do not always begin at the same step. Some projects begin with an idea or sketch, while others begin with existing patterns, samples, grading, or technical documentation already in progress. No matter what stage you’re at, most projects move through development in a sequence similar to the steps listed below.

Product Development Process

Show us your illustration, sketch, or concept, and we’ll translate it into a working pattern that establishes the shape, proportion and fit of your design, which becomes the foundation for everything that follows.

Next, we’ll review your material choices and sew your first sample, establishing the construction method, equipment needed, and technical details that will guide production.

Your pattern is then graded to the size range you’ve chosen while maintaining the intended shape and proportion, giving you a commercial-grade pattern ready for small-batch sampling or production.

Finally, we’ll bring your materials, construction details, and technical information from all the previous steps together into a tech pack, creating a clear reference for your manufacturer.

As you move into manufacture, we provide ongoing guidance through our Founder Support membership to help you understand factory requests, evaluate your options, and make decisions as questions arise.
