@seahorse OH here's me thinking linen is made from cotton, but the internet tells me it's made from flax?? Well, I had no idea. :D
I think I tried hemp and found the softness to be a type of softness I didn't like, and it's less flexible than cotton? But perhaps they are making more different hempy yarns and blends since I tried it.
BUT I have tried bamboo, and that was very soft and flexible, bamboo grows really fast, and the yarn is antibacterial. For drape, it reminded me most of cotton.
