Blue quilted duvet cover with white piping

Hey, I lost my blue quilted duvet cover yesterday around 7pm near the coffee shop on Gloucester Road, just after the Alma Road junction in Bristol. It's a CozyNest double-size duvet cover, cotton blend with a soft sheen, and the piping along the edges is a crisp white. There's a tiny yellow star embroidered on the top-right corner, plus a small coffee stain on the inner seam from yesterday’s spill. It also has a faint diagonal pull along the bottom hem from a washing mishap. It was a gift from my grandmother and carries a lot of sentimental value—I’d really appreciate getting it back if anyone spotted it.
