Cream duvet cover with navy piping, monogram JL

I lost my cream queen-size duvet cover yesterday around 3pm near the Starbucks on Grand Ave in Laramie. It's from SierraLux, made of soft cotton, with dark navy piping along the edges. There’s a small coffee stain on the back corner from a morning spill, and a discreet monogram 'JL' stitched in the lower-right corner. It meant a lot to me because it was a gift from my grandmother, and I really need it back. If you found it, please text me; I can meet up anywhere in Wyoming to retrieve it.
