I don't really care about lines before. What I care about is reasonable price and soft to the touch. But then, lately I have learned a lot about linens, like it's materials, made from what country, tread counts and so on. But still I don't care where it's made and the chemicals they have used during it's process.
All I want now is a blend type of materials, 60% cotton with 40% polyester. It's soft to the touch and to my skin, does not wrinkle that much and I'm happy with it so far. Oh! thread counts, well as long as it's 300-500 treads counts, beyond 500 in my personal opinion is too heavy and un-breathable.
