The best resource for manufacturers large and small...
We talk to multiple manufacturers every day, people and companies making and selling everything from a single sewn product to thousands at a time. Although the scale is different, many of their questions and needs are similar. And frequently we refer them to the same place: Fashion Incubator: Lessons From The Sustainable Factory Floor.
With Kathleen's blog, a marvelous set of forums, absolutely incredible tutorials, and so much more, I visit the site regularly and I recommend it to everyone involved in any aspect of "sewn product manufacturing". Kathleen Fasanella's book, The Entrepreneur's Guide to Sewn Product Manufacturing, is amazing and well worth the cost. (I also recommend buying it simply as a way to support the site and to let Kathleen know how much you appreciate her knowledge and her willingness to share it -- seriously, it's not that common for people with this much experience, intelligence, and passion to put so much effort into helping other people get it right.) Kathleen's also available for pattern services, consulting, and instruction -- and talking with her for a few hours just might be the difference between your concept's ultimate success or failure.
Why do I spend so much time raving about someone with whom we're not affiliated? It's simple, really. I believe in what Kathleen does; I think she's sharing invaluable knowledge that can keep companies in business (and in the US -- and that's one of our big goals here too: sustainable local businesses). She led the fight to inform people about the CPSIA and is still active in that fight, and her site is absolutely invaluable for both beginning and experienced manufacturers. Whether you're considering a boutique line or are already in the midst of full-scale production, I highly recommend visiting Fashion-Incubator.com.
The demand for sustainable and organic fabric products is increasing yearly, and many of our customers are helping fill that need; it's wonderful to know that Fashion-Incubator appreciates and respects the need for sustainability and helps our customers succeed.
