Reddit reviews Fitting and Pattern Alteration: A Multi-Method Approach to the Art of Style Selection, Fitting, and Alteration

Oh, I understood.

As for resources, here's what I suggest:

A good sewing class at a community college. I took classes at a fashion-oriented one and in under four months I had learned how to sew on an industrial machine and done several seams and seam finishes, basic hand stitches, two types of zippers, facings, a skirt with zipper, darts, waistband, and closures and a fairly complex woman's blouse (it had 14 pieces). At the end, I didn't do any of these things as well I would have liked, but I knew the fundamentals and what I had to improve on. All projects were in some kind of cotton because it is easy to work with.

In the second sewing class, I learned welt pockets, made corduroy pants with a waistband and fly, and sewed a wool jacket with patch pockets and a bagged lining. Again, I learned a lot, but there was still plenty of room for improvement. Then I took tailoring and couture classes and menswear classes.

A community college setting is good because there's a curriculum into which they have put some thought and by law, they have to make sure you do the work. It's also usually cheaper than private classes if you qualify for the in-state rate.

If you can afford it and want to do things on your own schedule, private classes are great. I would have a teacher show me how to fit and modify a pattern and teach me to sew it. One source for teachers is the Association of Sewing and Design Professionals.

Online, I recommend the University of Fashion because the teaching, in general, is very good. For pattern making and draping, they tell you the sequence of videos to watch. I think that the sewing videos aren't organized that way, but if you need to look up a technique, it's very easy.

If you want a complex project, I recommend Susan Khalje's The Couture Dress on Craftsy. Even if you don't use the pattern that comes with the course, she teaches very good methods. Couture-style sewing is actually good for beginners because there are many more steps that give the sewer more control. It was only after a basic couture class that I really began to improve because I needed to break down the process more. Khalje also teaches a lace skirt class, but the lace used is pretty expensive. As you may know, Craftsy offers frequent sales.

There are many good sewing books, but any edition of The Reader's Digest Guide to Sewing is decent. It's a really encyclopedic home sewing book. If you ever look into tailoring, Tailoring: The Classic Guide to Sewing the Perfect Jacket and these books for men and women are very helpful.

Elizabeth Liechty's Fitting and Pattern Alteration is usually considered the most comprehensive book on that subject.

All these books are available in the library if too expensive to buy.

Fitting and Pattern Alteration: A Multi-Method Approach is a good book.

Learning to draft patterns is an excellent skill, but it's only the start of the process. Those books teach the reader to draft for an industry dress form. Almost no real person is shaped like that. The next step is to fit an actual human body with non-dress form proportions and asymmetries. I just ordered this highly recommended book.
