Socks wear out, and that seems normal and obvious. Dishcloths and linen kitchen towels also get rubbed a lot, until they get holes.

Sofas and carpets and rugs generally don’t. Sofas are all artificial fibres these days, so they’re almost eternal. Wool rugs somehow also seem nearly impervious to wear; I wonder how that works.

But this cotton rag rug is apparently not eternal. Ten (?) years of footsteps have worn the fringes down to nubs. The body of the carpet is perhaps a bit flatter and slightly thinner than it used to be, but not visibly worn. I wonder how many years it will last.
