Of course I salute your reverence for pure linen teatowels ; I share it but mine must be red and white. Dh doesn't get it but he knows never to abuse them.
He just doesn't get rags at all. He knows that old cotton clothes end up in the rag bag , saved for one-off use then get chucked. What I just can't get through to him is that a man sized pair of denim jeans , however old, cannot be used for mopping dog sick because they are not a rag. Or soft or absorbent. To become RAGS, most old cotton clothes have to be cut up. Into squares, The right size. Unless they are already quite small, like his y-fronts. There is no need, or point, cutting defunct Y fronts into squares because they will be too small to have any use. Rags are kept in the rag bag. So its easy to find a rag. There is no need to take out all the rags and wonder which one to choose or what it used to be... before mopping dog sick or wiping engine oil. Priorities.
