The older Vikings like the 1+ had a serpentine type stitch. It was on a card and you could adjust it. Older Pfaffs before the CV had Maxi stitches you can program in on the machine. The CV series probably also has it. These are embroidery machines, though.
I've used all the stitches for crazy quilting, some work just fine for straight quilting. Use your imagination. Grab some fabric and try it.
Certain machines like my Pfaff don't need a separate walking foot. They have IDT built in. The Babylock Quest has a good IDT.
