Thank you everyone! I made a stack-n-whack some years ago via a class and it had the corner triangles. When I joined this group a few months ago, I liked the OBW's without the triangles MUCH better but knew if hand-sewing was involved, there'd be no OBW in my future but as this can be sewn on machine, I'm in!! Thanks to all I will definitely check out that tutorial, Caroline. Thank you!
