I now buy linen (you might need a mortgage tho’). Can be grown in Europe, needs far less water as a crop than cotton, and the more you wash it the softer it gets. And no need to iron as that makes it less soft!!
And they last, and last, and last…
French grown is most expensive, but also other countries.
This is where I bought my last lot

La Redoute also do linen that is less expensive.
