Answer:
Flat as a leaf, round as a ring. Has two eyes, can't see a thing.
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
My first is in some but not in all. My second is into but not in tall. My third in little but no in big. My fourth in port but not in pig. My whole is made in nature's way. For clothing, rugs used every day.
I always run but never walk, I sometimes sing but cannot talk, No head on which a hat to place, You always look me in the face.
I grow where no flower grows, where no light touches the walls, up or down, that I don't care, was here before people were.
I am a band that does not perform, sing, or act. What am I?
