I am building an Armoire that is in two sections. The top section is 45 1/2" tall. Each side and the back are wood/plywood panels. I am considering adding a cross stile to each panel for additional support and was wondering if there was a rule of thumb as to where this stile should be placed. 2/3, 1/3; 60/40 or just where you think it would be a good fit.
Or is it even necessary? John
