I ran baffles from to top (ceiling) to the overhangs. The question is I ran out of the baffles and they are about 14" short. I assune they should run right into the overhang area. Am I ok leaving them where they are before I insulate or do I need to run them to the bottom? Also, I'm installing faced R-30 insulation in this area (which is a knee wall and will be used for storage) should I install a vapor barrier (plastic sheeting) to help prevent air leaks?

Thanks
