They are probably either tineola bisselliella or tinea pellionella. I have ordered traps for both. I am not too concerned about the sculpture itself: the adult moths don’t chew. It’s the larvae that do the chewing, and they prefer dark places. I have numerous small felt-covered sculptures around the studio. They’ve been there for years, and nobody has chewed holes in them. Probably the caterpillars are nesting comfortably in a box of fleece. That’ll be a nasty not-quite-surprise when I find it.
I know they’re just minding their business, but still: little bastards.
