I use the same procedure that several have suggested; above the standard
inner cover.  For me, the IC opening size seems totally non critical.  I
place an empty deep super above the inner cover and the "feed frames" above
that as several have suggested.  I make sure that there are no entrances
where robbers can get in from outside the hive, as does everyone else.  

What I do that is different is; I place the "feed frames", "up-side-down".
The bees do not like placing honey in a cell that is "slanted down" thus I
have never had them add new honey.  They only remove it.

Occasionally I will have wet supers with some crystallized honey (cotton,
turnip and the like).  If the bees are allowed to clean these frames, they
will most often leave a white residue in the cells.  HOWEVER if the frames
are "up-side-down" ("top bar down") while the bees are cleaning they ejected
the residue and you get cleaner frames.
