lots of people 'free motion quilt' on their domestic machines- and do wonderful jobs - you do not need a long-arm to 'free motion quilt' . generally when using your domestic machine you use a walking foot keeping your feed dogs up for straight line quilting- you use a 'hopping foot' (sometimes called a darning foot, or free motion foot) with the feed dogs down- disengaged or covered for free motion quilting. I've seen many machine quilted quilts that were absolutely stunning- done on a domestic sewing machine- it just takes practice, patience and the desire.
