Thanks for the tip, Mitch! The hinges are the kind that bolt into the side, not the front or back, so any screw that fits into the 1x4 should work (I guess up to about 3"
). I was thinking, that because the doors are somewhat long in proportion to their height, and particularly that the hinges are not that far apart from each other, that it might not be a bad idea to attach a small block on the inside of the last 1x4, that the doors can rest upon when closed -- so that at least when the doors are closed, the weight of the door is basically resting on canopy, instead of applying a kind of torquey force on the hinges. The doors aren't actually attached yet, I was going to paint first. Assuming I am allowed to get anywhere near a can of paint again, that is...
