My best friend taught me when I was pregnant with my first child. Simple patterns with few pieces (avoid Vogue like the plague for a beginner). McCalls, Simplicity and Butterick are good ones to start with. Follow instructions to a "T" and you should be fine. If you purchase a sewing machine, a lot of places offer free beginner classes for learning about your machine. If not you can easily sign up for a class, they are not expensive. I am sure if you google "beginner sewing instructions" you will get a lot of hits. Read a pattern a couple of times before you start any project, until the methods make sense. Visualize as you go. I know that sounds simplistic, but it works. Use your pins, some don't like to use them, but starting off one should. Keeps stuff in place, but don't run over them, it wrecks your needle and your pins if you do. Just slip them out before they hit the edge of your presser foot. Sew at slow speed to begin with, as you feel more secure and your seams are consistently even, ramp it up a little bit. Most of all have fun. Don't stress. This can be such a fun past-time and a wonderful creative outlet. Keep a seam ripper handy, it is inevitable, even accomplished seamstresses occasionally have to take out stitches and re-do.
