if its a smaller quilt, like 4 feet or under, i just quilt with the foam extension like in the youtube video.
when its over 4 feet i quilt with the flynn frame.
my sewing machine has a very small throat (about 5 inches) so the first thing i do on the flynn is either some stitch in the ditch or basting stitches (if i don't want any stitch in the ditch on the quilt).
this way i'm able to pull out the middle rod and i can work on more complex quilting designs without having to start and stop the design.
with the middle rod in place you have to work across the length of the quilt, then move it forward and quilt that row - this makes it very difficult on a 5 inch throat to do an 8 inch feathered wreath motif. so i work quickly to remove that middle rod.
once the middle rod is out you can quilt how ever you like because you can move the quilt forward and back as desired.
