Stitching on a Cardinal’s cap

STL

Not available

This clue plays on the double meaning of "Cardinal"—it refers to both the bird and the St. Louis Cardinals baseball team. The "stitching on a cap" hints at the team’s logo, which is often embroidered on their hats, and "STL" is the common abbreviation for St. Louis in sports. So, the answer is a short, clever nod to the team’s initials rather than literal stitching.
