Hi Carol,
I have a new Janome with the built in walking foot, well I took the SID foot off as someone wanted to have a look at it but then couldn't get the foot back on. Eventually got it back on but the back piece which grabs the foot wouldn't attach. I was fiddling around trying to get it to attach and must have touched something I shouldn't as the whole lot fell apart so now I have 3 pieces I don't know how to re attach. The book is doubly gook to me. Will have to wait untill I can go to town on Tuesday till I can have the lady in the sewing shop show me how to put it all back together (do much better myself when I am shown)
Thanks for asking
