Gray quilted duvet, Bedding & Linen

I lost my gray quilted duvet yesterday around 3pm. It’s queen-size with a charcoal-gray cover, soft to the touch, and it has a small teal embroidered initials 'PP' in the bottom-right corner. The edge features white piping and there’s a tiny coffee stain along the hem. I last had it in the parking lot behind the Fort Dodge Public Library on Central Ave after stopping there yesterday afternoon. This duvet was a gift from my grandmother, so it has sentimental value, and I’m really hoping to get it back.
