I have used both Marti Michell's book and the "Divide and Conquer" book - love them both. I have a pretty good throat space on my Elna but still find it too small sometimes to maneuver. I don't do a lot of free motion quilting - find it too stressful - so I use my walking foot most of the time. I highly recommend Leah Day's Walking Foot Quilting book, too.
