Sandy, quilting is to knitting what scrambling eggs is to a souffle. You can quilt!
There are thousand of resources on the 'net, and kits and stuff to start out with, if you want. There is nothing at all to it, especially as you can already sew. I made my first quilts entirely by hand, then machine stitched the tops, then rented time on the big machines that do the actual quilting for you. The only limitations are your imagination and the amount of time you have. Well, maybe space, too. A big problem right now.
I'm very partial to the wedding ring pattern, have one on my bed. My favorite quilt is a very old one made from pieces of the dresses of my husbands grandmother and her sisters.
