FreeSewing is open source software to generate bespoke sewing patterns, loved by home sewers and fashion entrepreneurs alike. Industry sizing is a bunch of lies. Join the slow fashion revolution and enjoy clothes that fit you.
FreeSewing is not a company. We do not sell anything. We do not have staff or employees. We do not have an office. We do not get paid. Our website does not contain any advertising. We do not track you or sell your personal data. We do not violate your privacy.
Pick a design for something. Key in your measurements (if you're not sure how to do it right they'll teach you). Customize the pattern if you like. Print it out, pin it on, and get sewing.
Or you can use their software on your own: https://github.com/freesewing
