I just discovered these "Cobbled" threads; very neat idea!
I haven't done a great deal of cobbling yet, but I love having another source of inspiration, as it is something I like to do.
As for lighting (I'm an Enchanted Lighting junkie), this is nothing super complex or fancy, but I somewhat recently came up with a way to mimic a glowing Thieves Trove.
Another, in an outdoor setting:
I wish they'd add an interactable, "resplendent" version of the thieves trove furnishing; something with the glow, that we could stash a couple of items in. Like a mini-storage chest.
Or, at least, a resplendent version of the thieves trove furnishing, if not a storage piece.
