I have a Janome and love it. I have had 3 of them. On my machine the setting is Mode 2 #39 and two clicks (positions) to the right for a scant 1/4" seam. Save it in the memory. I also use a 2.2 stitch setting. Mode 2 #39 is the Patchwork Piecing Stitch. With this setting I use a 1/4" foot specially made for a Janome.
