When you want to make your own clothes, I'd say: buy a good sewing machine. A good tool is necessary (ask man, they always buy a good tool, it's half the work) . You'll get very frustrated if your machine doesn't work and you can see it on the clothes you've made. It's always handy to follow a course. Pick one where you can learn how to draw your own patterns. When you understand the basics of drawing, you can change every pattern in the one you like. Pick something simple to begin with, sportstrousers for example (not stretch). A good book is always handy. Best are the books were they explain one technic at the time. I only know dutch books, but I'm sure there are enough english books with that topic. I wish you a lot of fun sewing and showing your own clothes
