I love linen, but it kind of sticks. As a bottom sheet, it would have a tendency to not allow sliding as much as those made from a combination of cotton and poly. I think that a combo sheet on the bottom and a linen top sheet could be perfect. I'm one that uses a flat sheet on the bottom (king size for our queen mattress), because my husband was always pulling fitted sheets out. I also buy vintage sheets off of eBay, and find vintage cotton/poly percale to be the toughest and smoothest, vs. 100% cotton ones. We've had our current bottom sheet for at least 5 years. It's a combo sheet with a Montgomery Ward tag on it, of all things. I think sheets have really taken a dive.
