Good girl! It's great that you want to learn to sew. I think you'll probably find it a valuable skill for the rest of your life, just like knitting and other fiber arts.
I learned to sew many years ago mostly from books and the instructions that come with clothes patterns. And there are a lot more books out now that cover both the basics and the advanced stuff.
It's probably a good idea for you to get yourself a good sewing encyclopedia to learn the basics. Work with the instructions that come with your new sewing machine and go over that info until you've mastered it. Repetition, repetition, repetition!!!! Then when you know how the machine works, the sewing encyclopedia will get you started on the basics - cutting out a pattern, sewing a straight seam, etc.
Then as your skills increase you can investigate specialty areas like curtains/draperies, quilting, and other home decor projects.
Mainly, though, have fun with it!!! Learning to sew well can be very rewarding.
And one piece of advice I got that's served me well over many years and many garments....never cross one seam over another until you've pressed the first seam open. (or always press garment seams as you go for a really finished look). Then when I would finish something like a jacket or jacket and skirt set I'd always have them professionally pressed before I wore them. That sets the stitches in the garment and you've got a great looking tailored piece from then on out.
