The stairs to the upper floor are divided. I think that adds a lot of interest to the landing. I cut the frames out of two thicknesses of cereal box cardboard and then glued balsa risers and steps onto that, just like the big staircase only different measurements.
They fit together perfectly. The underside joints are reinforced with thick glue for added strength, then the whole thing (except for the wooden parts) is coated with gesso before painting white.
The steps are stained with a burnt umber wash. The rail is cut out of one piece of card double thickness. I will cut it as needed for making the top floors railing to get it all to fit and look right.
The steps are all dried and ready to fit into the landing hall.
