From personal experience I can say the drop/leave/return/decorate process works quite well. I would advise however that if you have any NPCs in the house with you (housecarl, follower, spouse), and particularly if you have more than one NPC in the house, that you go in a room with doors you can close and drop any items there.
If you drop something in front of an NPC there is a chance that he/she will remark on it and either ask if they can have it, or just give it back to you. Had a follower do this with a dragon claw I was planning to put out on display. Kinda hard to drop something and leave if some well-meaning NPC keeps stuffing it back in your inventory.

If there is more than one NPC present there is a chance they will both call dibs on the dropped item and then fight each other over it. Supposedly this happens if the item is valuable, but I've had a follower and housecarl almost kill each other over a wooden plate.
The funniest one was just last night, Argis and Calder came to blows over a copy of Uncommon Taste that I was trying to put on a shelf in the kitchen. You know I keep coming home and finding one or the other of them slaving over the cooking pot - but I had no idea they were
that serious about the culinary arts.
