Navy quilt with ivory trim, monogrammed A.K.

I lost my navy quilt last night while I was at the State Capitol area. It's a queen-size quilt from Pottery Barn, soft cotton with ivory piping along the edges, and a small coffee stain near the bottom corner. The quilt is monogrammed with 'A.K.' in light gray thread. I last had it around 3pm yesterday near the parking lot behind the downtown library on West Main Street in Bismarck. It holds sentimental value—my grandmother gave it to me, and I'm really hoping to get it back.
