Cream duvet cover with blue piping, king-size

I lost my cream king-size duvet cover with blue piping yesterday around 3pm. I was at the Starbucks on Water Street in downtown Port Huron, sitting near the window while I chatted with a friend and folded a load of laundry in my bag—think I must’ve left it on the chair when I packed up. It’s a soft brushed cotton duvet cover, king size, with two matching pillow shams that fit snugly. The left edge has a tiny, almost hidden blue fox embroidery and there’s a faint coffee stain near the bottom corner from a late study session. This set has sentimental value—it was a gift from my grandmother—so I’d really appreciate getting it back if anyone found it.
