I would suggest that you visit the sites below. Some are for aspiring designers, some are for reading material. I would also suggest that you call your local (or closest) community college) They usually have a "community education" or "Learning Annex" type of program. At my local Community College you can get one day or 2 days workshops, varying in hours and price. usually 29-99 dollars. and the "teacher" is someone in that chosen field. You can also call your local fabric stores, they usually hold beginners classes and advanced classes and even one on one sewing classes. They will also be the ones that can direct you best to local pattern makers, seamstresses and other small business owners that deal with design. You can contact these peple and become their interns to learn as much as you can hands on or simply ask them questions.

The link for the book on Amazon didn’t come up so the books name is :

"The Fashion Designer Survival Guide : An Insider’s Look at Starting and Running Your Own Fashion Business"

Best of luck
