Anyone can quilt, you are definitely not over your head. Not to worry, a lot of us are using older machines without bells and whistles. Do you have a quilter near you to help you one on one? Local libraries are great places to meet quilters and to pick up some fantastic techniques in all those quilting books. Sometimes I'll find a good resource that I add to my piles at home but most of the time I just borrow them.
Also, be sure to check out your local quilt shop...and once you're hooked, you'll be looking at every quilt shop wherever you go.
Happy Quilting!!
