Placeables my good fellow, I love to use them as decorations. Im just a guy who has always leaned towards darker designs. I have always liked the whole barbaric conquerer theme for this game and have long been an advocate of more brutality and gore in the game. Here were some ideas from a previous thread:
I want thralls chained to boulders and in manacles, placeable torture devices such as the throne of agony & iron maiden and stretching rack we can place them in, crosses to place them on, taskmasters to whip slaves on the wheel of pain, human hide rugs, cups made out of our enemies skulls, placeable hearts, furniture made from blackened bones, rows of heads on spikes, a Dafari on a rotissery, black fountains which spray blood.
Basically in terms of the skulls, I typically make rows of Weathered Skulls on Shelves. And also a row of them on the ground on either side of my walkway/entryway path. This was the original thread if you are interested.
Now regarding the Fur/Hide/Pelt Rugs. Im also a man who prefers the head and paws off myself. However to please both camps I I suggested that we simply have 2 variants of each rug; one with the head an one without. I essentially said in my suggestion that many of the pelts we find (not Hide) have no real use beyond Leather and Tar production, which are beyond abundant. And that some pelts, eg-Crocodile, Wolf, Bear, Bat, etc should have a reskinned version of the existing Fur Rug. Again here is the original thread (which Im surprised did quite well on the votes) if you are interested.
You seem to be a person whos ideas are geared more towards mechanics Eladrin? Im better with just inaniment placeables.
Ps-sorry for the wall of text.
