I have done the Hoop Sister's Flying Geese and Feathered Star. The backing is floated under the hoop at a point in the embroidery process. You use a special ruler to trim away the extra batting and stablizer leaving your fabric untrimmed. You trim the fabric to half inch then after blocks are sewn together you make sashings using the half inch of fabric border. The hoop sisters have a video showing how to do it. It is way more work than I want to do so I skip the step that adds the backing material and add a complete back when I am done. I then stitch in the ditch. For the feather star I had it LA and she did a large stipple because there was no clear path to SITD.[ATTACH=CONFIG]478834[/ATTACH]the video from Hoop Sisters is in connection with their current Mystery Quilt.
