if you use the regular foot or walking foot, there will be LOTS of turning of the quilt under the arm. do to my limited skills in sit down fmq, this is how i do it, though. if you use the darning/fmq foot, there's not so much turning, but you have to keep your stitches even with the movement of the fabric. IMO neither is an easy task. i love your panel and good luck in whichever way you go.
