Lost dark blue microfiber comforter with white spots left on a couch at Gulfport Public Library.

I lost my favorite dark blue comforter, which is made of soft microfibre, at the Gulfport public library last week. I had it with me while I was studying and think I left it on one of the couches. It's hard to miss, as it has a few little white spots from my pillow that likely weren't washed out entirely. Please let me know if you find it; I really can't sleep properly without it!
