Behind the sofa
What was hidden is reconstructed from the surrounding surfaces rather than smeared over.
Clearing
Empty the room without moving anything.
Take out the furniture, the clutter or one particular object, and get back the room as it would look bare, with the floor and skirting filled in behind it.
Start from empty
Clearing first and staging second usually beats restyling a room that is already full.
Remove one thing
Take out the previous owner’s wardrobe and leave everything else exactly as photographed.
