Q: why does it say "linen" multiple times yet it's 97% cotton?

There's almost no such thing as genuine linen fabric made from flax anymore. The texture, weight and weave of this fabric is linen-like. Wikipedia is your friend: "The collective term 'linens' is still often used generically to describe a class of woven or knitted bed, bath, table and kitchen textiles traditionally made of flax-based linen but today made from a variety of fibers."
