I have been collecting shelving units to build some stairs - so I can create a second floor. I tried to make some steps with them and didn't have much luck! I would love to see how you guys have done this. What is the best way to "stack" the shelves (or whatever you used) to create stairways? How did you "set" the flooring when you did get the stairs done (stack bookcases then set a rug on top??). The new Gorowyn and Neriak homes both have high ceilings and would be perfect for an upper level! Thanks for any and all tips or ideas!
