samwinolj did indeed come to our house on Sunday and the closet in the library has now been reconfigured for efficient storage of guitars. :) The basement banister is reattached, although we may do some more work on it to slide it a bit higher on the stairs, as the new hardware is a bit different (and sturdier, I hope!) than the old.
Large parts of the library floor are now visible.
The couch has vanished under an avalanche of boxes, but we'll get to that soon. :)
