Why don't people put carpeting on their desks anymore? It would make for a nice, spongier writing surface, although it would require a writing board to go on top of it. Turkish desk rugs were all the rage in the Renaissance, at least in Italy.
And speaking of carpeting (you knew I'd return to the subject!), there's a huge amount of carpeting rolled out into the street right now, far enough that I'm mildly worried a car might run over it. Presumably this is a convenient place to cut it for the rooms inside.
