White queen duvet cover with navy piping and monogram

I misplaced my white queen duvet cover with navy piping yesterday around 3pm near the CVS on Franklin Street in Chapel Hill. It's a 100% cotton cover with a small gray monogram 'A.J.' in the bottom left corner and a tiny coffee stain along the left edge that you can only see up close. It's in good condition otherwise—no tears or pilling. This duvet cover is sentimental to me; it was a gift from my grandmother, and I’d really appreciate getting it back.
