Well I am one that wrote earlier about this, and how it was unclear what to do especially chain stitching. I now do both, set my stitches at 2, and I make sure I leave a little thread between the pieces that way can leave some thread hanging. Don't ask me which one works but they are working. I don't have my pieces coming unsewn and causing me to make wonky blocks, well I won't go that far but at least the wonky isn't because of the stitches coming out lol.
