Yes for quilting your sts set at 2.2 is to short...
Try a 3.0 to 3.5 is the normal unless doing a barjello or
a srtip pattern you are going to be cutting..
Another thing to also think about the more stitched per ich the weaker the seam will be.
Think of it this way a picec of vinal the closer the stitches the easier it tears.
Good luck,
