I have a quilting function on my machine, but I have never tried it! Just found it not too long ago when I had the manual out for another purpose! I will have to try it.
If you are new at this, I would Stitch in the Ditch, and then do a little Free motion squiggling for fun. Don't make it too difficult for yourself.
If you have a walking foot, use it for your SITD. It will keep your top and bottom together. Are you going to spray baste? Check out some of the tutorials here for help. Use Search.
