I'd love to know from you all however, where could I find (or at least what keyword could I use to find) the appropriate attachment to do free motion quilting?
Look for a low shank darning foot - sew-classic and other on line companies sell them.
The feed dogs drop on that machine - there is a little knob on the lower right that turns and the feet raise and lower - it may or may not be stuck up with dried up oil.
