Cream duvet cover with blue piping

I lost my cream duvet cover with navy piping, queen size, yesterday around 3pm near Walmart on Main Street in Worthington, MN. It's a soft cotton Threshold duvet cover, with piping along all edges, and there's a small coffee stain near the zipper on the bottom corner. I use it every night and it feels like a little comfort from home, and it's sentimental since it was a gift from my mom. If anyone found it, I'd really appreciate getting it back.
