Sounds like flannel to me. I use flannel sheets in the winter as they are warm and soft.

Answer 2

They might be made from bamboo...yes! bamboo! It is about 90% softer than cotton and easily made into different textures.

Answer 3

I do not know about the indented squares, but there are sheets on the market made form T-shirt material.  Those are really soft.  Yo can get them in Target  I believe.
