Sounds great right? Imagine yourself making the pieces for your closed you had dreamed, and of course this is far away to be a new idea, since the last 400 to 2000, we know that women like you and me on the past dreamed to make their own cloths, of course some of them learned how, but this was a small proportion of them.
Right now the things remain very similar, cloth design is a kind of career that really still catch the attention of several ones, but at the same time is a field that is followed for a very few populations no matter the gender. So on this first stage you have to ask yourself if you want to continue this idea and maybe become this your career or just see something about it but never take this seriously.
If the first option is the accurate and the desire of your heart, then you should consider to professionally learn it on a college as the cloth designer career. Is usually a short one but is the perfect program to learn and get the most essential tools to start a professional enterprise on the fashion world?
If your answer is more like the second one, well you probably should have the classic machine at home or take it borrow from your grandma or mom, you can buy it too but if you are thinking about this as a test you should use the first option.
Then you need to find the tutorial, and internet, specially YouTube has a lot of them to make some basic cloth pieces, on this videos you will see the materials you need and you can properly make your first cloth and some pieces for your closet.
