Question: What celebrity, famous for his iconic sweaters, only wore cardigans that were knitted by his mom?

Answer: Mr. Rogers. Fred Rogers is a neighborhood friend to many of us and was known for opening his show with a wardrobe change into a cozy sweater and tennis shoes. His mom, Nancy, knitted every single sweater that Mr. Rogers wore on his program, including one red cardigan that now belongs to the Smithsonian.
