I just found a new post on the Janome site that says I have to buy another shank attachment for the DC1050 in order to use that foot. I think this is new as it wasn't on their site a few days ago. I was looking for something else and this was the latest post. More $$$ of course. I want to buy fabric and thread not shanks!
Thanks for the info everyone. I will give the darning foot another go but I sure don't know how you could darn with it.
