Kathy, all my "free motion" is done by tracing or copying a stencil or pics of the design, spray basting or pinning to the quilt and then quilting it. The worst part is the tearing off of the paper, but I have found out that parchment paper works really well. Another thing I did with a quilt I made for my granddaughter was to do squiggly lines instead of just in the ditch, then I didn't have to worry about going out of the ditch (because they were all out), but that quilt was just plain blocks. Also I've been told that the squiggly lines hold up better than straight ones. I also believe that cotton batting is easier to "free motion" because it seems to not "bunch up" or slip on the back of the quilt as much.
