When I went down to Arizona for Nebula Weekend, I stayed in my sister Angie’s guest bedroom. The bed was fitted with the softest, most comfortable sheets I’d I’ve felt, so I asked her what they were and where she had found them.
The sheets are Pure Beech Jersey Sheets, made from 100% modal, which is a fiber from the beechwood tree. I bought some after I got home. They can be purchased at Bed, Bath & Beyond. They feel much more comfortable than the 100% cotton sheets I was using.
