You can also check on u tube and at the library for books or tapes to check out on the subject. I agree that a serger and ball point needle are the best way to deal with knits. But like everyone says, check your built in stitches on your machine. There should be some there for knits. Your sewing machine manual should give you a little instruction too.
You will be surprised how easy it is to work with. Don't be afraid of it.
