Navy Pottery Barn duvet with initials A.L.

I lost my navy blue Pottery Barn duvet cover yesterday around 3pm near the Northpark Mall entrance on Rangeline Road in Joplin. It's queen-size, with crisp white piping and a tiny embroidered 'A.L.' in the bottom-right corner. The fabric feels like soft microfiber, and there's a small snag along the bottom hem from a cat scratch—barely noticeable but definitely there. It was a gift from my grandma and means a lot to me; I really need it back.
