+1! A red carpet like this one, maybe? I've also asked elsewhere for a carpet that is like a mossy patch for the groddle floors; now I'd also like one that is a mossy uralia patch. The Yeti Fur rug could also be tinted different colours for an easy set of additions.
I also like the idea of a "red carpet" carpet - one that lays lengthwise across the walking path and that could be joined up end-to-end to make a longer fancy red carpet.
