Online, and crediting my husband for this one: Sheets and Giggles. (and hello, that name!) We like them.

“ Eco-Friendly Eucalyptus Lyocell Sheets
Our sheets have a near-zero environmental impact, with up to:
- 96% less water used than cotton
- 30% less energy used than cotton
- Zero pesticides or insecticides (cotton uses ~16% of the world's insecticides)”
They are very soft, even after laundering a lot and having a dog sleep on them and “dig” a hole before sleeping. And good customer service.
