I am thinking of adding another level, I would take the cheap way, shelf brackets, possibly homemade, maybe hang one foot off the wall. want to know how much clearence I should have and how long the run to the next level should be, I think now is a good time to consider this, B4 I have to rip up a bunch of scenery. Anyway, any help, suggestions, of any sort are wanted. What should I use, how should I use it, I am not sure how to begin. Pleas give any possible help.
