It seems I may have gotten it wrong when referencing which adapter might be needed for Berninas if one wants to use the Janome low-shank convertible free motion quilting foot set with the ruler toe added.
I am so sorry. I am still waiting to hear back from my Bernina girls to verify, but it looks like the #77 adapter foot doesn't work. Two lovely readers are awaiting the #75 adapter now, so I hope we can figure it out.
I have updated the post, Free Motion Foot and Toe Follow Up.
Update: I have heard back from one of our dear readers and Bernina girl, KaKnitter and she reports, " Great News, the #75 adaptor works with some modifications. The Free
motion convertible set has a slant on it and the adaptor does not slip
in all the way unless you metal file down a little bit of the #75
adaptor. My dear husband fined tune it perfectly. I am thrilled. :)"
I am so happy that the foot worked out for her and that there are options for Bernina users and others to use this great technique for ruler work!
