This only works if you are doing an all-over pattern, not a custom quilting job. If you are doing custom quilting and there is no way to sneak to another area, you have to stop and secure your threads, either by tying off or going back over your stitches. Some quilters can be nearly invisible on backtracking and some can't - I can't so I choose to tie and bury.
What is "the SitD grid"? I have never heard of that!
