I only do straight line or stitch in the ditch quilting - which I think I do respectably well. I do have a Pfaff with the integrated walking foot which helps immensely - and I also closely pin the layers together .
I do admire some of the FMQ and what some of the long-armers do.
I have decided to not fret about my lack of skill at FMQ. (Notice - I did not say that I cannot - because I don't know that - but I do know that I am not skilled at it - yet)
