You can get a walking foot and darning foot for your machine, as your machine takes short shank attachments. I've quilted for years on old Singers that don't have dropping feed dogs. You don't need to cover them either. Just set your stitch length to 0 and with your darning foot on give it a try on a small quilt sandwich.(top fabric,batting and backing). FMQ takes practice, so don't think that you will be successful on the first tries.
