I have the Janome 6600 and recently looked for the 1/4 inch accufeed foot. My LQS only carries it as the foot with a marked needle plate. I can order just the accufeed 1/4 inch foot on-line from a sewing supply company but wonder why Janome packages the foot with the needle plate. Couldn't find any information on the Janome site. Does anyone know why the plate is combo'd with 1/4 inch foot?
