The only thing I dislike (intensely) about my Pfaff is that awkward great lump of plastic that is the buttonhole foot and the fact that there is no alternative to automatic buttonholes. It's great on a nice, flat piece of cotton but anything else and the stress levels soar. I was given a lovely, tough, little vintage machine (a 1970s Lewenstein) with a 4 step buttonhole and I mostly use that.
