I twisted invisible thread into my Janome Horizon bobbin case yesterday - she is now in the car waiting to go to the machine doctor. I then used an older Janome with a ordinary walking foot, OUCH, awful. The Accufeed foot is amazing and you do not realise it till you don't have it. I set my Janome at 5.5 width for a 1/4 inch seam, however I always feel that the seam is a tad wide. What do other quilters on the forum set their Janome machine width at for a 1/4 inch seam please???
