My mom is letting me have two small square tapestries, maybe 7" x 7", so I will use those affixed to a foamcore backdrop to simulate tapestries insulating a stone wall.
I also just bought a black fainting couch jewelry box and a black wire jewelry holder that looks like a bookshelf or display shelf. I will fill the jewelry holder with books and knickknacks appropriate for Lucian.
Then all of these pieces together will create the impression of an opulent [if chilly] castle. Pictures below. [Polybag-Monster is the Ebay seller for both items, if you're interested.] Further bulletins as events warrant!
