I just remembered the first way in which I tried quilting actual motifs, I traced the design onto greaseproof paper and pinned it on top of the quilted sandwich then with an open toe foot, low pressure and feed dogs up, stitched on top of the lines. You then rip the paper away afterwards. Only problem with this way, is you have to rotate the quilt around as in normal stitching and this will be impossible on a large item. The echo quilting I did free hand, just by sighting the previous line of stitching in the top corner of the open toe foot as a guide.
